You might be able to integrate into lemmy by adding your podcast rss into a lemmy community made for your podcast. Lemmy users could subscribe to the community and follow/discuss there. Feels like a redundant suggestion if your cms already supports activity pub, but as far as lemmy integration that’s the only way I can think might work.
There was already a wave of bots identified iirc. They were identified only because:
1 the bots had random letters for usernames
2 the bots did nothing but downvote, instantly downvoting every post by specific people who held specific opinions
Turned into a flamware, by the time I learned about it I think the mods had deleted a lot of the discussion. But, like the big tech platforms, the plan for bots likely is going to be “oh crap, we have no idea how to solve this issue.” I don’t intend to did the admins, bots are just a pain in the ass to stop.
