Does twitter ban multiple accounts that have same link?

Let's say I create 50 accounts with all accounts having the same link in their profile but each will have different bio. Each account is created on a clean ip. Would twitter ban all those accounts for having the same url in their profile?

I am sure Twitter crawls all the links. If your links is points to a legit website, Twitter will not ban. However, if the website is shady Twitter will notice + 50 different accounts pointing to the same one, will lead to bans.

Not really, there are many twitter users who are members of an organization or company with the same link in their bio.. it depends on the link. If it's spammy and people will report it then yes. You should also make sure you don't have common followers (the equivalent of common friends on fb) on the 50 accounts.
