I think it would have been best to have made an announcement and to have started with those with 0 games. This would purge a lot of the forum spam bots. Of course some alternate accounts would be lost, but that's unfortunate. Instead some accounts that were active on these forums at some point are gone. I sincerely doubt all of them played less than 10 games (I know at least one of them posted in the ToS Discussion subforum, and most of them played FM and I doubt somebody would come to that without playing at least 10 games) so unless each of them requested deletion... yeah I have my qualms.
Permabanned accounts should've been the first victims. Gets rid of the plethor of bot accounts from October.
