Hexbear had been around for like 3 years before lemmy.world was even created, that’s why they have such high activity numbers. Most of that activity is reactionary memes and rants about the media topic of the week, and hence largely meaningless and irrelevant content several years later.

My server is defederated from hexbear as well, because they tend to disrupt discussions with their aggressive, cultlike behavior. I wanted to like them, but they quickly wore out my optimistic goodwill with their puerile immaturity and unearned self-righteousness.
