Sorry for the delay, I wasn’t notified of your reply for some reason. When I enable relays under attack, it’s a mix of bot accounts impersonating others and replying with copies of random notes, plus occasional LLM-generated content. Unfortunately, there isn’t much I can do about it with hidden word filters. My strategy with Amethyst has been to temporarily stop downloading notes from affected general relays and re-enable them later. As Will said, attacks seem to come and go, often jumping between different relays. 

 Yep the impersonator bots are the worst the replyguy is easy just add GM's on the mute word list and he will be gone.
