Well, I would say reading isn’t that hard. All that’s needed is no life and too much spare time 
. Needed likes are a different story, because given likes will lead to inflation of reactions and getting likes tells about others’ reactions.
I don’t even know my TL. I don’t need that information. Probably I’m at TL3 because I can use proofread and translations, unless the limits of AI use are downsized. But hey, I can give those rights to someone who hasn’t the time to read practically everything here, if I can keep proofreading, translations, and explaining 
.
But at a meta level.
Those limits should be as low as possible until some problems start to arise. And after that, there is a real reason to tighten them up. Sure, sometimes an anticipatory counterattack is needed, but not so often (unless the niche of a forum is risky for spamming).
