IP address is part of it @LumpySpacedPrincess
I have seen a GC mum who was banned saying that her teenage son's account was banned too, the only common factor being the IP address.
When Jenn Smith was banned she said that someone else in the same building but a different household was also banned.
Twitter is purging accounts that were trying to evade prior suspensions
14 Aug 2018
" . . . In many cases, banned users would simply create a new account using a new email address and then continue to tweet. Twitter’s means of identifying returning users has been fairly simplistic in the past. To make sure banned users didn’t come back, it used information like the email, phone and IP address to identify them.
For it to now be going after a whole new lot of banned accounts who have been attempting to avoid their suspensions, Twitter may be using the recently acquired technology from anti-abuse firm Smyte. At the time of the deal, Twitter had praised Smyte’s proactive anti-abuse systems, and said it would soon put them to work.
This system may pick up false positives, of course – and that could be why Twitter noted that some accounts could be banned in error in the weeks ahead.
Reached for comment, Twitter declined to answer our specific questions and said it could also not go into further details as that would give those attempting to evade a suspension more insight into its detection methods.
“This is a step we’re taking to further refine our work and close existing gaps we identified,” a spokesperson said. “This is specifically targeting those previously suspended for abusive behavior.
