I moderate a community on this website, and a user broke the rules so I had to ban the user. I’m concerned that this user may have alternate accounts on other Lemmy websites and may evade the ban. How can I find these alternate accounts?
How can I find these alternate accounts?

Which comm do you moderate? I don’t see any in your profile. Your account is brand new so I think you might be fibbing.
I’m guessing they created a new account for anonymity, so others couldn’t connect this account with their mod account.
Which is pretty ironic if you think about it.
I moderate a true crime community
You are a true crime community. Cyberstalking is not cool.
When they break the rules again ban their new username…
Until then, find more constructive things to obsess over.
There isn’t anything built in to share problematic IP addresses, but there isn’t anything stopping instance admins from sharing. I believe there was talk of a universal ban list to subscribe to, no idea if it ever got published. Though, if a user has taken the effort to maintain multiple separate accounts then they might be using VPNs as well.
An IP ban also created the risk of banning others unintentionally. ISPs which use CGNAT will have a large number of users coming from the same IP address. So, banning one IP could ban a large number of users.
Hopefully you won’t 🙄
