The rate limit on posting reward only affects top-level posts. Comments are not affected. The bot accounts wang and cheetah, for example, have not yet even created one top-level post, only comments. So they would not be affected by this.

Thanks for the comment @arhag makes sense - upvoted

Actually the cheetah is useful for pointing out possible plagiarized content. I guess we will see which bots are altruistic or just greedy.

I don't think they will be dead. The good ones change their algorithm to match the new rules.
