He spammed for 50 mins using 6 different accounts.
I'm no mod but I think giving chess.com staff the account names would get your problem solved faster than vaguely complaining about it.
I did, and thanks to Martin_Stahl, all of the spammer's recently used accounts were closed. However, this didn't happen until after the spammer had already spammed for 50 mins, and he'll probably have 10 new accounts tomorrow. It's not fast enough to stop him. What I'm campaigning for is to have more live chess mods, such as myself, so that the spammer can be stopped immediately.
Please don't interact with him. That just feeds the troll. If nobody pays any attention to him except for staff/mods closing his account, eventually it will cease to be fun for him and he'll get bored and stop.
