Autoban that appears in modlog is permabanned by the mods. I wonder what calci did to get permanbanned.
All those accounts = calci. Posts may not appear too bad until you multiply it times 14 and realize he made ~200 similar posts in the past 2 days.
First ban was the ban, second was because I already had a tab open for that profile and hitting ban again was faster than refreshing the page to see if I had banned that one.
The last 2 were IP bans (rest were regular account bans) after I was done to increase the amount of evil on those IPS for a while, they'll decay over time.
tl;dr: sometimes people spam so hard they get banned thrice.
