As Jwein mentioned, "spam delete" deletes everything that a user has done. Its an option during the banning process, but only head mods have it to avoid mistakes being made. So I perma the bots to avoid future spam and cgi when he came back online used the spam delete.
We try to keep an eye out for spam bots, but we don't catch everything. If one spams your wall send a mod a pm and we'll take care of it.
Will do, thank you.
If you demand respect or gratitude for your volunteer work, you're doing volunteering wrong.
