Anarchy is a political structure where there’s basically no one in charge, right? But wouldn’t that just create a power vacuum that would filled by organized crime, corporations, etc.? Then, after that power vacuum is filled, we’re right back at square one, and someone is in charge.
Are there any political theorists that have come up with a solution to this problem?


Again, effort. Why bother with yet another power tripping admin when they can just hop on to another instance (or ideally, save their energy to actually do something meaningful in real life). It’s just a niche online forum run by neurodivergents.
True. It just so happens that all the other anarchist instances also happen to like us. Funny how that works, huh?
Yes, I’m sure that all the people you have an agreement with agree with you.
