If you head to Twitter right now, the vast majority of bots are blue checks. It seems to actually encourage the opposite, where you trusting that someone paying $8 for an account makes you even more likely to fall for slop
I think twitter is an odd-one-out here, twitter as a whole has been heading down hill ever since the acquisition, and I wouldn't be surprised if many of those blue checks are officially sanctioned bots. Especially given the way so many of them push the same narratives that Musk does at the same time he does.
I'm not convinced that twitter is actually trying to get rid of bots. They're OK with boosters/scammers/propaganda/agitation mills, they just want a cut.
