Because they let go of a lot of moderation team and I could see my obviously-bannable reports rejected. (Saying some minority doesn't deserve to live, apparently doesn't break rules after the takeover)
Also obvious scams are still rampant. Say you have a problem with a crypto wallet and you'll get lots of bots offering "help". Not solved for many years.
And yeah, as the sibling comment mentions, those are arbitrary chosen numbers from the company itself. Do you expect them to publicly advertise they're doing badly in some way?
