Problem with Chat trolls

[Chadi]

There is someone continually trolling my chat room (under new accounts constantly) somehow and I don't know how he's doing this for the following reasons:

1. new registrations moderated first (he was not approved yet, but "awaiting email activation"
2. Real Chat (software) is set to usergroups 2, 6, 7, and 38 only. Awaiting email activation usergroup as you know is 4.

This is the template I'm using in various places (header, footer, arcade main page for example) that contains the entrance link. Is something wrong here?
