There are many issues which make Facebook unsafe for people with brain injuries to use. There are many hackers and other evildoers on Facebook. Users have to watch constantly to see if their name and photo are being used. Many people are oblivious to problem, though, and it can take a long time for good people to see that their names and identifying pictures have been usurped. In the meantime many people they actually know will have befriended the bad-clone person. That can lead to problems for these other good people,
It used to be that if a third party reported a hacked account to Facebook Facebook would make a report to that third party as to the resolution of the matter, but it doesn't seem to be happening anymore.
Facebook makes it difficult for people with brain injuries to use because it is endlessly making changes to monitize itself. People get used to one format and suddenly Facebook makes changes which confuse many users. Facebook is now moving ordinary pages to its Meta business suite. Pages might not be related to any business enterprise but this new move by Facebook doesn't appear to be optional. It can be very difficult for people with brain injuries to figure out whatever the business suite is about. This new heavy-handed business move by Facebook is causing a lot of difficulty for some people with brain injuries.
Facebook likes to cut off supposedly bad accounts, but often accounts of good people have been hacked and Facebook does not adequately jump in to deal with the hackers. Instead, Facebook is content to wait weeks on end to review hacked accounts. Actual humans who work at Facebook apparently are not looking into said kind of situation early in the process. And there is no way to contact an actual human being at Facebook to ask for more details about the ban and/or for the Facebook user to explain what happened. It seems it would be a good idea for Facebook to protect the injured parties, namely the people with hacked accounts, and for Facebook to go after the hackers instead of innocent users, but it doesn't appear that that is happening..
It would be helpful if Facebook would explain to its members what steps it is taking to get rid of the hackers. Identifying them publically would be good. Facebook operates in its own realm, however, and is quite inadequate at letting the public, or at least its good members, know what actions it is taking or has taken to deal with particular hackers.
There used to be a way on Facebook to see what country a person was coming from and if the person had recently switched languages, say, from Chinese to English. It was handy to see if the person claimed to be a US citizen from, say, Los Angeles, but the person had very recently switched from using Russian to using English. Facebook removed this handy sleuthing tool. This kind of information was useful for administrators of Facebook groups where potential members are looking to join.
There are probably countless organizations using Facebook for networking, etc. But one has to remember that adminstrators from said organizations don't really control what is going on on their Facebook pages and groups. In the end Facebook controls it all. We can't be lulled into thinking that it is safe for us to use Facebook.
