People still post, it is just that it is more likely to be people asking about technical issues than anything else. I don't like to sit on Discord, because it is too hard to keep track of conversations, and I prefer to just skim static posts rather than deal actual real time conversations. For visits, we still get plenty, because people utilize all the old posts for technical help on VN issues all the time. A lot of the other sites that had that information are long gone, so a lot of VN-readers treat us like some kind of archive for troubleshooting.
We do still get people asking for recs, but more and more it is stuff I can't get involved in, since I really only played untranslated VNs after the first six months or so.
Incidentally, the amount of bots is probably about ten times what you think. I prune at least ten for every one you report, because most just put their adlinks in their profiles rather than posting threads nowadays.
Edit: also the ghost bots that post meaningless and seemingly harmless posts that the bot goes back and edits a month or more later to add a link to. The key for those is that they tend to use real people names for their handles... so newbies, please don't use your real name or something that might be a real name for your handle, because it is automatically suspicious here, lol.
