@Alda It sounds quite bad from those images, but I haven't read the rest of the story or background.

Techncs is a pretty big instance which has been around for quite a while. The other day I read something from Gargron (from a while back though) in which he recommended the instance and admin. There's bound to be a lot of good people on the other side of the block you're considering.

Personally, I'd wait another day or two to see how this plays out. If things go bad, block. If things go well, keep it in mind to block later if it happens again.
