I have a year old lurker account on X. I've never made a single comment with it. But 35 attractive women are now following me. Zero men, zero unattractive women. I doubt that it is the result of the animal magnetism of my likes.
I expect if you chat to them you'll find they have some interesting crypto opportunities to invest in, from my experience. There's a lot of pig butchering stuff out there (https://news.ycombinator.com/item?id=39778486).
I blocked a bunch of those accounts and the number of rando hot girls trying to get me to follow them dropped really quickly. You may give that a try. Maybe they have some very rough algo that does attempt to stop those follow varieties that you block a lot of
They're trying to simulate real accounts by following people. Blocks are likely a strong signal for anti spam. So if the spammers notice that you block bots, they won't want to burn accounts by following you, and will instead follow accounts that don't block bots.
probably the rando hot girls are all run by the same big bot farms, or bot farms sell suckers lists so if you are a sucker for one rando hot girl bot the others soon find out.
This could have been it, they could have been all under the same umbrella chud organization and it was really just one actor who spotted my account for some reason.
It's a microcosm of the whole darned web.
