This is a period of explosive growth and adjustment for Lemmy, it'll take awhile for things to settle down and for us to see what people's true colors are. Hopefully anywhere that actually harbors hateful or troll content will be marginalized and the mainstream instances will be properly moderated, but it'll be a continual battle since such people always want to find new ways to spread awfulness. If we're lucky, instances that have good track records will federate with each other. If not, people can vote with their feet.
