Even have the audacity to send me an email with “someone tried to log in with your username and password!” Yeah, that was me clowns. :-p
Out of nowhere, they locked me out of my account, then they asked for my phone number, and I had to put in a code received through SMS. But that was not enough, because then they asked for a national ID card (the gall!). Of course I did not send it.
However, I kept trying to log in with the password and SMS code for a couple of days hoping that the ID requirement faded away, and now they say that I "have reached the maximum number of attempts. Please try again at a later date.". Well, duh.
So, now I have a ghost LinkedIn account with my face and my data that I can't even delete.
I'm seriously thinking about asking a bunch of people to mass report my account for racial hate speech or something so that at least it gets deleted.
This is where being an EU resident would be handy.
Of course, using it as a weapon against your competitors is the unsaid reason for these operations...
Facebook once balked and demanded my driver's license scan to keep using the account for security purposes or no more login for you. I called their bluff and abandoned the account. A few months later I tried again and suddenly the driver's license wasn't needed anymore. Then I stopped using it for YEARS until they sent me a single email with a link, which LOGGED ME IN to the dormant account without asking for a password on a new PC that had never used facebook before. I actually don't even remember the password at this point but it is still logged in!
