I'd be happy if GoG hired me to help handle Spam control... I'd make a list of things to look for, then do a bulk find using SQL, then block things that match that. (i]Naturally i wouldn't do it blindly, but i'd still need direct DB access...[/i]).

But even if i'm just one guy, i'm sure i can do quite a bit...
Yes. With no name attached likely means the account was already banned but the comment remains. I already contacted support about that a while ago regarding being unable to report older spam.
