I guess no one will agree with me on this but I think you should name names. I know I would not mind my name being mentioned because I have nothing to be ashamed of. Also naming names might just embarass him/her enough to replace the original junk with decent stuff or at least not do it again.

I hate to rehash, but had Rene done this we would all know by now.

Protect other chippers, name the culprit.
