Social networks are actively introducing new strategies to get rid of the swarm of bots and fake pages, but sometimes these strategies do not work quite right. And this was exactly the situation with Twitter today, as thousands of users discovered their accounts to be blocked for no reason.
The email, that the 'banned' Twitter users received suggested the accounts "exhibited automated behavior." So, if you click the follow button too often or use a third party app to follow back, check your mailbox as you account might had been blocked to “protect Twitter from unauthorized logins.”
The massive blockings started shortly after another striking news about Twitter hit the Internet. The account of Twitter's CFO, Anthony Noto, was stolen. It had been sending out spam tweets containing potentially malicious links for about 20 minutes before it was recovered at 11.30 a.m. It's quite likely that Twitter's team was quick to introduce new security measures to protect the accounts, however it didn't work as was expected. Currently Twitter is working to resolve the issue and unblock the wronged accounts.
