Ew yeah, I clicked on that reference link on one of his negs and was treated to a disgusting death pic.  OP, why would you post that here in any context?  I can't read French so I don't understand what that thread is all about.

I'd also say this doesn't appear to be an instance of moderator abuse (though I don't know the whole story).  If anything, bitcointalk is under-moderated if you compare it to the average discussion board.  It's not likely some French mod somehow got a hard-on for harassing you--and in any case, it's only for 7 days.  You're damn lucky you didn't get permabanned.
