When Communities launch on Steem, for the first time ever people will be able to create communities, on the internet, that they own.

I'm curious to see how this plays out in reality. Will there be a rush to essentially "squat" popular communities/categories/tags? If so, what can anyone do about a completely mismanaged category/tag? For instance, what if someone were to "buy" the cryptocurrency and cryptos communities and then proceeded to post their own referral links and shill their favorite tokens, then "moderated" everyone else's posts to make them invisible or sent them to the bottom of the "hot" or "trending" lists?

What do you do then, other than create a new community like "real-cryptos-community," or some stupid crap? Will there be any built-in protection to mitigate or prevent the above?
