What does this mean?
 

When you go to someone's profile, and it says 'banned'? Does that mean a user is banned?

Yes, Someone's Profile that says "Banned" has received a ban on trisphee. Either it be a temp. or perm.

Yep, that's what it means.

Wow. I went to welcome someone, who I had just seen join. You know? Where it shows the latest person who joined, and there it was. Banned. Hm. Oh, well. Thanks guys, for your help in answering my question. :)

Most likely it was a spammer that we caught pretty quickly.
