Others have said similar things, but TikTok/Instagram/YouTube accounts posting short daily "best of" videos or something like that would work well if enough users coordinate to boost the accounts. Could probably even monetize and fund the site or buy drugs.
I don't even think it would be that hard. Pick a format and stick to it, use AI voiceover and captions, and just do slideshows of memes, funny comments, etc. Slowly include Hexbear jokes, explain the lore, drama...people love this kind of shit. There are literally millions of commies on TikTok. I've seen fullblown leftists with over a million followers.
If you can get your hands on some Rick Simpson Oil (RSO), it'll probably help a lot more than smoking or edibles. Hard to find if you're not in a legal country/state, but very worth it if you can.
