No one is destroying the community.
Only a few accounts that have been spamming and farming have been blacklisted.
The accounts were run by bots and were farming curations + self voting with alter accounts, while their automated giveaways posts have been giving next to worthless prices. Like packs of cards or "scrap" worth less than $1, while farming between $6-$15 per post (depending on the farming account).
The users were given a suggestion of starting creating original content or declining rewards on these spam giveaway posts but they refused the suggestion as they seemed to see no sense in using Hive if they cannot continue with these farms.
