Tag your posts with the appropriate newsgroups. Anime posts get tagged as #rec.arts.anime, programming goes in #comp.lang.* as appropriate and so forth. Remember excessive crossposting is discouraged!
So Usenet is kind of like a federated forum but it works more like email than, say, Mastodon. Every NNTP server has messages to all the newsgroups it carries delivered to it from an upstream server, and every time you post you send a message to your Usenet server that then in turn propagates it upstream, it's all relay based. Instead of all the messages going into a big fucking hellpile like Mastodon, though, it's organized into newsgroups, each of which has a name that describes its major topic. Back in the day it was very active for text posts and threads, so you'd post a message about, say, anime to rec.arts.anime.misc (the miscellaneous chat newsgroup under the rec.arts.anime tree) and everyone who reads raam would get it and could reply. The groups were/are, as shown there, organized in a hierarchical tree, kinda like domain names; "rec" is for recreational topics, "comp" is computer related shit, "sci" is science, and good ol' "alt" is the "fuck your stupid taxonomy" tree that had its own stupid taxonomy that was a lot like the regular one, just... under alt.
Usenet's still there and if you wanted to shitpost at a bunch of spambots you could write a post in raam all about how Akane isn't a lesbian, comma, just like in the old days
lmao there's no comp.lang.rust because I don't think there's anyone enabled to create new groups in comp.lang anymore but there is an alt.comp.lang.rust now
