If you check out lemm.ee and lemmy.ml you can see that we have a bulk of ~100 hexbear upvoters on new pushing socialist content to the top of the feeds. By banning reactionaries, they lose this bulk of upvotes and comments that make their reactionary posts relevant (despite being controversial). I've even noticed a shift in instances not federated with hexbear posting more socialist leaning content due to this influence.
