Anyone know good twitch detection tools

banned some people on stream and now they are coming back with multiple accounts to continue to troll or even just talk to others in chat about random things. They are clearly using a VPN or a different location to bypass the shadowban feature. how do I tell if they are the same people trying to sneak back in?

besides if they start trolling in chat again or account creation date because some of the accounts are not brand new but I have a feeling it’s the same people. any way to get more details on a user or see if it’s connected to other accounts that were banned in the channel? don’t want to mistake an actual new person
