I thought for a moment it was happening to me after coming off of just simply upvoting things about lemmy, but I think I've seen other people report that the reddit site is currently on and off shitting itself. (Is it hug of deathing itself? Plenty of people are coming for popcorn.)
I think it would be too fast for reddit to incorporate auto shadow code into the api itself to time out requests from users engaging with lemmy/kbin things, but I'm not really sure.
