Several friends have been inexplicably banned by FB recently for no reason that they could see. One had a Troll, de-friended the Troll who then made a complaint against her, causing FB to issue a ban.
Something is not quite right with this picture methinks.

I had to re-verify myself with FB a few weeks ago for no obvious reason. This involved a series of trick questions followed by identifying 5 friends from tagged pictures. Still don't why but it feels like my account got flagged somehow for something.

Meanwhile the author of TFA is in the UK and suing the Data Protection Act to demand the reasons. That will also be interestng to see how that plays out.

Facebook can of course do whatever they want after all, we're the product not the customer. But these kinds of cases need lots of public exposure. Especially now they are a public company. Just maybe then it will keep them somewhat in check.

Lol, you know about SNs banning people, don't you, Julian ;-)

Good point though re: the 3rd party mix which is common amongst the successful SNs of today and how it could really screw with a person's use of the net if they rely on these services for authentication.

Probably best practice to always register an account with an email address for contingency purposes.

There's definitely a big impact where the functionality of a site (like FB) pervades other, unrelated, sites. That is the impact of unified logins.

Makes you think.
