This thread just blew up tbh, unlike anything I've seen here. Mostly, our news bulletin megathread sometimes breaks 1000 comments, when there's big news happening. Most other threads never hit 500. This one seems like it was bait to draw in lib commenters from the wider lemmyverse after federation and it worked. The user in question came in pretty antagonistically and is replying to all the replies they got, so yeah it's probably a lot of replies to deal with but they also brought it on themself and it wasn't anything coordinated. I myself have been engaging with this person, but just the same way I would have argued with anybody else here that I disagreed with over the last 3ish years.
