i think the comments about the age of this site, changes and moderation are a little unfair. there are a number of active mods, and there have been a bunch of updates over the last couple of years.
are there still bugs and quirks, sure. i almost enjoy the occasional "chat leak" now.

munchies' note re: blocking reducing community engagement got me thinking about the "format" of a site, and how that influences how users interact. for instance, this site is primarily message, forum & chat driven. blocking in regards to personal messages and chat seems pretty straightforward, but in a forum situation it becomes more complex. especially when threads sometimes are active for years!
when i think of social media, i think of x, bluesky and feabie - posts are made, they can be shared, re-shared, and they are not dispersed and not cohesive. comments can be made on the share of the post, and never relate back to the source, etc. in that situation, blocking is much more important because you want to exclude someone's material from your "feed" which is curated by an algorithm. whereas in a forum you just don't open the thing and ignore the thread.
there is another forum that i frequent that has one active participant that i find really annoying. (i am sure others think they're great, not judging - just my taste.) whenever i see they are the last to respond to a thread, i just bypass it. i ignore it. i am not interested.
so i kind of understand the webmaster's stance - what would blocking do our forum? there was one troublesome user some time ago (initials: j.s.) who, i believe was banned from the site. so as long as these individuals are being dealt with, i would say i think it works, doesn't it?
