Yeah, it was the Shoppa game #20811 (not the WxW).
Alright, good to get that misunderstanding out of the way then
I think you should do a better work about the insults/flames if you want to get a greater league.
This is the biggest problem of Wn and the ban is the only way to make people change.
You already pointed out the announcement yourself. Although I do agree (or I wouldn't have posted that announcement), we should be careful not to be handing out warnings too lightly. As MI already pointed out, language is a problem as well with Banca.
I also can't find anything in the chat other than the things MI already pointed out, but it seems to me he can't handle losses very well since you were beating him pretty badly. I personally wouldn't go so far as giving him an official warning for this, though we should clearly try to avoid this escalating.
PS: You should also forbid people who's not concerned, to post on threads.
Such as Crash who's saying "Rofl" in a non appropriate thread (and which is mostly apparented to flood and flame).
(Nothing special against you Crash... at least in this case.)
I actually did post something along that line in another thread, but Dub-c pointed out people should be able to post meaningful arguments and I can't say I disagree with that. crash's post is harmless (mostly because it doesn't seem to make a point or really say anything useful at all), so again, I see no reason to interfere there.
