So it's whatever.
The stuff on lounge is far more restrained and less disruptive. Odds are the mods are keeping a eye on it.
My bet is it will calm down after the election is over or dude's shitchan ban expires.
If you see true spam or off topic shitposting report it then wait a day. If it stays up then mod thinks it's not crossing the line yet. If it gets removed then you did your duty.
This doesn't apply to the abyss though. Don't bother reporting shitposting there. Everyone including the staff will just laugh at you.
