Netral tag + report moderator = Case closed
Nor was I going to do that. I have two of the 4 quoted in the OP on ignore. I was simply going to put the other two on ignore as well, but I didn't know about polo7 being a scammer with an active flag against him.
Thankfully it seems possible that the member you replied to has finally given up on the account because it has been nearly a week since his last appearance. As it serves no purpose for him now other than to simply be a nuisance and seek attention considering he knows his tags will not be removed (and he probably will be unable to enrol it on any signature accounts), he will probably use his time to concentrate on his other accounts.
What is it about any account that has 777 in their name makes feel nauseas?
