Maybe an insta-ban for newbies who only post 'when lambo' or 'when airdrop'?

Uhh, that's why they're newbies? I'm not taking their side, its just that you might want to take it into
consideration at some point (instant ban, that's pretty harsh TBH). If you don't like what you see, then report them. But on the other hand just help them, and what I mean is that, don't just provide them what they need - guide them to what they
have to do.
Or filter out everybody who writes English like a 4-year old but has a legendary / full member-status. I seem to come upon those a lot lately.
English isn't my native language but at least try to do some effort. I improved my English by watching the Fresh Prince of Bel Air. Also improved my Carlton-dance-moves.
If you realized it by now, the ranking system back then was not taken into effect, its like just how long have you been here (thanks to the Merit System then).
Like you've said, maybe English is not their native language. But you're right they have to make some effort if they wanted to improve.
