I just added the mod alpha said to and even that has not seen any of these accounts as spam 0.o
Update: The mods are picking up the users now. I just banned everything from one hosting company from where they seem to be always a source for the spam.
Hopefully it will be ended now. We have won this battle for sure, But we may not have won the war!
