Heya! I have an onlyfans and it's really hard to get followers. It's different for girls, I'm sure, but it helps a lot that I keep my Twitter as active as possible and post tease pics there to get people to check it out. I also make sure the Twitter isn't JUST pinups, I try to engage a lot and get people to my page with interesting comments and such.
Oh, and a lower price really helps, that's the kind of thing people can set as a recurring payment and kinda forget about, as mean as that sounds.
Still, I don't have a ton of fans soooooo... Maybe I'm not doing it right either! Lol
