Here’s a neat one: chip away at last.interi.org +remind recur:3d
I went through my old site a while ago and moved over all the interesting conversations from comments. When I only had posts without comments left, I created this task. Now, every three days I log in and check spam comments, and whichever posts have them I move over to talkgroup. In this way spammers are helping me decide at random which remaining posts to move. 
Hilariously, when no comments are present, I just move the most recent post, and while I started this thread 20 minutes ago and checked my email, having not looked at my archived site, the most recent post is entitled, “New apartment routines”.
