There's no point, they will knock out all offshoots. If another replacement blossoms up it's just more gridlock, censored words and warnings until we get the hammer. If you're actually serious about making them feel the fucking heat listen to this:
Make normie looking Reddit accounts. Keep the posts kosher for a while. Aim for comments that could get you high karma in fresh threads so you could be at the top when the threads blows up. After you've made it, edit in hatefacts, or tell them to read Culture of Critique or whatever. I'd rather not erase the entire post after editing because the normies need to get engaged and focus on the post first, the real potent message must be delivered at the end. Don't add in "edit:"
Same for threads, if you're making text posts try to appeal to the common bugman. If you manage to get to the hot section of a subreddit or even /r/all, edit the text post into an informative post about things AHS would start fuming over.
They'll be playing whack-a-mole forever since in the beginning there's no way to know who's a legit person and who's doing psyops. Subreddits would have to start adding in more precautions somehow (account older than 1 month etc.), driving away innocent new users from the website.
Also make an account where you're roleplaying as an AHS/SRS user. Get to know how they behave (tip: they're not like the caricature we have in our heads). You must fit in and contribute. These are sleeper agent accounts, their purpose is to gain mod privileges at their own offshoot subreddits. Build reputation among them and then start instigating inner conflict. I'd also unironically campaign against getting the_donald shoahed, because that has the potential to burn the entire site to the ground and create massive resentment against Silicon Valley as a whole.
Most of all, don't get too into this. Do this as a hobby on the side while having a real life.
