don't really care either way about the ai thing but deffo ban moldy posts. we already have !funny@lemmy.world or !memes@lemmy.world for that kinda stuff
the 0.19 implementation is so half-assed I genuinely think the Lemmy devs just don't want that functionality but expected quite a lot of backlash if they outright said as much, so they decided to implement something that ticks the box in the "wanted features" list without having any effect
afaik it only blocks communities and explicitly lets users from blocked instances through
the thought behind banning it and explicitly allowing "US acceptable zones" is so we can shove all US discussions there and let people talk other things in peace, and those who want to talk US politics can go and mess shit up there, far away from the rest of us who just want to chill and be silly in peace :3
doing it on a "case by case basis" does not help when the intent behind the hypothetical rule is to enact a Lemmy wide change in the atmosphere of the platform
.world is unique in that because of its size it has kinda ended up being "Lemmy" to most people. I very much doubt the people posting porn on .world care about instances and federation and just treat .world as a centralized site
tbf Lemmy's behavior is documented and standardized (https://codeberg.org/fediverse/fep/src/branch/main/fep/1b12/fep-1b12.md) it's just that their fallback code for instances that don't federate the Lemmy way also boosts the target posts for each update as opposed to just once on creation like you'd expect
(talking about microblog fedi here, Lemmy/threadiverse is it's own thing)
don't do hashtags. hashtags (especially common ones like #memes) are overrun by repost bots and low quality garbage.
the trick is to be on a small-to-medium instance you vibe with (1k active users seems to be the sweet spot. anything larger than 2k I'd avoid. do NOT join any flagship instances like mastodon.social), follow fun people from your local timeline, and see who they boost. and follow up the boost chain until your timeline is sufficiently fun.
he's just packaging (for the fleas)
