licy. its new policy is to place deceased members' profiles in a "memorialization state".41 facebook's privacy policy regarding memorialization says, "if we are notified that a user is deceased, we may memorialize the user’s account. in such cases we restrict profile access to confirmed friends, and allow friends and family to write on the user’s wall in remembrance. we may close an account if we receive a formal request from the user's next of kin or other proper legal request toegulations by deleting such posts, they noted that it was difficult to effectively police the individual users who repeatedly republished the deleted information.43
customization and securityve tweaked their profiles by using "hacks." on february 24, 2006, a pair of users exploited a cross-site scripting (xss) hole on the profile page and created a fast-spreading worm, loading a custom css file on infected profiles that made them look like myspace profiles.44
on april 19, 2006, a user was able to embed an iframe into his profile and load a custom off-site page featuring a streaming video and a flash game from drawball. he has since been banned from facebook.45
on march 26, 2006, a user was able to embed javascript in the "hometown" field of his profile which imported his custom css.46
in each case, facebook quickly patched the holes, typically within hours of their discovery. however, in july 2007, adrienne felt, an undergraduate student at the university of virginia, discovered a cross-site scripting (xss) hole in the facebook platform that could inject javascript into profiles. she used the hole to import custom css and demonstrate how the platform could be used to violate privacy rules or create a worm.47 this hole took facebook two and a half weeks to fix.48

minors
facebook has an age limit of 13, but no real method to prevent those younger than 13 from just entering a different birth date. efforts began in early 2011 to delete and ban the profiles of those under 13. it was estimated that 20,000 profiles are deleted each day. 49
one major controversy with facebook is its source of revenue resulting from the sale of user information to third-party applications. in february 2011, talks began in an effort to protect those under 18 from having their addresses and phone numbers shared with these third-parties.50
technical

disabling of user accounts
there have been complaints of user accounts easily being mistakenly disabled for violating facebook's statement of rights and responsibilities. the disabling is often automated and can be easily triggered by a user filing a report on an account, regardless of whether or not the report is legitimate.5152 once facebook disables an account, whether it does so for unconfirmed reasons or a suspicion that something may be awry, it is impossible to reinstate the account, partly due to lack of in-person support and partly because any attempt to do so sends the account holder into a closed loop.
facebook's statement of rights and responsibilities is often misleading. for example, it states that joining a school network is not a requirement, even though users are often disabled for not joining a school network.53 facebook has disabled user accounts for having names deemed to be fake despite being real.54 once an account is disabled, it can no longer be logged into and all public traces of it disappear.55
there have also been instances of user accounts being memorialized, even though the person listed on the profile was not deceased.5657
lack of customer support
facebook lacks live support, making it difficult to resolve issues that require the services of an administrator or are not covered in the faqs, such as the enabling of a disabled account.58 the automated emailing system used when filling out a support form often refers users back to the help center or to pages that are outdated and cannot be accessed, leaving users at a dead end with no further support available.59
difficulty in removing apps
once facebook apps are added to a profile they have access to all the users data. it is impossible to control what data is accessed by these apps, nor is it easy to remove unwanted apps.
downtime and outages
facebook has had a number of outages and downtime large enough to draw some media attention. a 2007 outage resulted in a security hole that enabled some users to read other users' personal mail.60 in 2008, the site was inaccessible for about a day, from many locations in many countries.61 in spite of these occurrences, a report issued by pingdom found that facebook had less downtime in 2008 than most social networking websites.62 on september 16, 2009, facebook started having major problems with loading when people signed in. on september 18, 2009, facebook went down for the second time in 2009, the first time being when a group of hackers were deliberately trying to drown out a political speaker who had social networking problems from continuously speaking against the iranian election results.63
in october 2009, an unspecified number of facebook users were unable to access their accounts for over three weeks.6465666768 on september 23, 2010, nobody within the uk, us, and latin america could log in to facebook. facebook quoted a dns failure. citation needed
upgrades
september 2008
in september 2008, facebook permanently moved its users to what they termed the "new facebook" or facebook 3.0.69 this version contained several different features and a complete layout redesign. between july and september, users had been given the option to use the new facebook in place of the original design,70 or to return to the old design.
facebook's decision to migrate their users was met with some controversy in their community. several groups were started opposing the decision, some with over a million users.71
october 2009
in october 2009, facebook redesigned the news feed so that the user could view all types of things that their friends were involved with. in a statement, they said,
stories your applications generate can show up in both views. the best way for your stories to appear in the news feed filter is to create stories that are highly engaging, as high quality, interesting stories are most likely to garner likes and comments by the user's friends.72
this redesign was explained as:
news feed will focus on popular content, determined by an algorithm based on interest in that story, including the number of times an item is liked or commented on. live feed will display all recent stories from a large number of a user's friends.72
immediately, the redesign was met with criticism with users, many who did not like the amount of information that was coming at them. this was also compounded by the fact that people couldn't select what they saw. immediately, groups formed, one getting over 1,600,000 within the first two weeks of the update.73
november/december 2009
in november 2009, facebook issued a proposed new privacy policy, and adopted it unaltered in december 2009. they combined this with a rollout of new privacy settings. this new policy declared certain information, including "lists of friends", to be "publicly available", with no privacy settings; it was previously possible to keep access to this information restricted. due to this change, the users who had set their "list of friends" as private were forced to make it public without even being informed, and the option to make it private again was removed.74 this was protested by many people and privacy organizations such as the eff.75
the change was described by gawker as facebook's great betrayal,76 forcing user profile photos and friends lists to be visible in users' public listing, even for users who had explicitly chosen to hide this information previously,77 and making photos and personal information public unless users were proactive about limiting access.78 for example, a user whose "family and relationships" information was set to be viewable by "friends only" would default to being viewable by "everyone" (publicly viewable). that is, information such as the gender of partner you are interested in, relationship status, and family relations became viewable to those even without a facebook account. facebook was heavily criticized79 for both reducing its users' privacy and pushing users to remove privacy protections. groups criticizing the changes include the electronic frontier foundation77 and american civil liberties union.80 mark zuckerberg, ceo, had hundreds of personal photos and his events calendar exposed in the transition.81 facebook has since re-included an option to hide friends lists from being viewable; however, this preference is no longer listed with other privacy settings, and the former ability to hide the friends list from selected people among one's own friends is no longer possible.82 journalist dan gillmor deleted his facebook account over the changes, stating he "can't entirely trust facebook"83 and heidi moore at slate's big money temporarily deactivated her account as a "conscientious objection".84 other journalists have been similarly disappointed and outraged by the changes.76 defending the changes, founder mark zuckerberg said "we decided that these would be the social norms now and we just went for it".85 the office of the privacy commissioner of canada launched another investigation into facebook's privacy policies after complaints following the change.86
may 2010
in late may 2010, the norwegian consumer council filed a complaint to the data inspectorate on facebook and zynga's breaches of the data protection act.87 the consumer council is previously known for initiating the case against apple's itunes which eventually led to the dismantling of apple's drm practices.88
