How small art accounts (some AI) grow so fast from 0?

Basically the title.

Also, don't say things like "it's all about engagement and replying" cause that's total BS. I've seen tons of accounts who do 0 replies, they basically just do normal posts. (Yes, they're good posts, but there's also so many X accounts with same quality posts but getting no reach at all).

I'm also pretty sure a ton of those accouts also didn't get help from another big accounts, although many yes, they have a large account and just creating new ones to try to get that "viral" spark again on new accounts. This leads me to think that X has some sort of algorithm exploit, and doesn't rly reward consistent good quality posts like IG does.

I don't even know how it's possivble for these accounts to create the accounts and grow so fast, cause i'm pretty sure you have like some days of shadowban cooldown that you have to go through first. But whatever...

I could even show example, but I don't wanna have everyone looking at the accounts I'm looking at.

Almost certainly uses bots or are part of some artificial growth group that all support each other. Then, with enough "engagement", they get pushed as relevant

I should also add that these accounts are SFW. Probably cause X algo pushes to viral these, and not the NSFW (which prob require more long-term sutainted account growth, and not random explosive growth).

Also, I can also say that a lot of these revolve around posting an anime girl with like a white background, doing a pose to viewer, and that's it.

I know before the "undress" challenges popped pretty easily, but now just raw pics without challenges.
