Here's what I think...
1) They will eventually see you in-game and end up impersonating you again. What you need is clan tag protection, not a change of tag
2) Don't make a new thread for everything new that happens with your clan. Get back to your first thread about your clan and keep posting there. It gets annoying when you see several threads in this section about one clan, ya know?

Edit:
I would reduce the clan tag's size. Have you even tried fitting your own name with it in-game?
