Look at his post history before today and you'll see a suspicious gap exactly a week long in which he wasn't posting. Just saying.

That user is back with ~43 one liners just today. Guess someone didnt get the message.
Modlog is two weeks.
When I look at the modlog, one of the last entries I see is this
Nuke user: N/A in topic #0 by member #402358This user registered on this forum on 12-Dec-14. Assuming he was nuked immediately afterwards, I am able to see entries for maximum 7 days.
Are there additional pages which I am missing?
Weird, it used to be 2 weeks.
IIRC there is also a limit to the number of entries shown, not sure if theymos said that or I imagined it though.
All I could find with a quick search was that the listed bans are apparently permabans.
All bans listed on that page are permanent.
