I’ve been recategorising old Teonn posts back into their category (many old groups have ended up in the general “archive” category" instead). Most of the time this is invisible, but in less than 10% of cases Discourse thinks its a new post and bumps it to the top of the “latest” queue.
Sorry, everyone. Just ignore the thread necromancy; its old stuff from 2010-13 and hasn’t changed at all.
