It’s not
It just gets boring arguing with the same 12 accounts. That said some of these people putting in a full days worth of work to keep the memes and other content flowing.

Reddit wasn't much different. Even at the beginning there were accounts everyone recognized.

Just do what I do. Block the people that post a crazy amount of things. Those people are probably just pulling from reddit /all/topalltime and reposting anyways so it's not like you're losing anything of value.
