How to flag account registrations from the same ip?

Is there a way to automatically flag a moderator when a user creates an account from the same ip as an existing account?

I don’t necessarily want to block the new account if the “Registration IP Address” or “Last IP Address” is a match for an existing account, but I would like a notification if that is the case.

At the moment I just look through the new accounts every week and check the ips, but that’s a bit… manual.

Shouldn’t be too hard to do in a plugin :wink:

追伸:このプラグインは、複数のアカウントを持つユーザーを(おそらく)特定するのに役立ちます:

これは非常に役立つと思います :slight_smile: 繰り返し荒らしを発見するのがいつも少し遅れてしまいます。
