Help – Multi-Profile Trolls

I’m new here so apologies in advance if I’m doing something wrong.
The version I selected may not be correct btw.

Ok so I’m helping out a friend with his site.
We know various people are playing the old multiple profile game, and it’s hurting the forum.
I asked the superadmin if he could make a list for me of all members – past and present – including the email address they registered with, date, and IP address. He said it would take forever and didn’t want to deal.
Is there a plugin that can do something similar to this?
Other than removing a bunch of people, I think it’s the only way we’re going to crack down on a few and send a message to the rest that we mean business.
Besides looking at email addresses, and IP addresses, is there any other way to catch multi-profiles?

Thanks
