A really good way I have found that doesn’t turn the audience against you like barbecuing souls does is to not speak to whoever you’re replying to at all. Openly say you’re addressing the audience and speak of your opponent in the third person

I like your idea. I would like to keep people on my side generally since if i think someone is actually astro'n my turf i want other people to chasing them off too, not me. Generally i lose my audience when i mention the possibility they astroturfing even exists, and I've always wondered why. I'll try your method out when i run into a 'turfer im sure about.

As far as any list, sorry i got nothin. I used to keep a list of suspect astroturfers on Reddit but I'm way too new on lemmy, still finding my way around.
