I think maybe the slow down of the summer (and the good weather) drove people away from their PC? I noticed it slow as well. And I do see a few from here over on the other look alike forum. There appears to be more activity over there. Mturk itself has been really harsh lately as well. The bot issue is taining the platform. I almost suspect that Prolific is behind it, I read the twitter threads from both, and Prolific is really attacking AMZN hard. So many little factors going on, but I know my most recent rejection, the req cited having to be extra careful because of the scamming levels on mturk. MAybe that is impacting everyone as a whole. Sorry you feel down though.
