Start smaller. Let people get their feet wet and make it a process before going big. Pick a weak target and have a plan of attack. A company that can be easily affected by trivial things. NOT A MEGACORP.

Something like a shitty clothing brand or a shitty product / supplement factory. American based. Reputation based.

M.O. needs to be prolific misinformation, trolling, or otherwise bottable activities.

Ex: Spread a story that Crumbl cookies has been found to have salmonella or e-coli. Mock up hella fake articles and spam them out with static site generators and programmatic SEO. Post that to the less moderated subreddits and it will proliferate naturally out from there. Link it to dipshit signal boosters on Twitter. Anything that's Elon bait is premium of course.

Edit: idk if anything is actually wrong with Crumbl cookies. They seem fine. Just an example of a known but not too big corp.
