for these popular accounts, the general attitude seems to be that - if you want it - you're going to have to pay for it, the funny part is that the asking prices are the same or even more for what the irl services cost, except it isn't as easy to get on the irl list
and another explanation is most likely AI bots now, there is zero filter there in regards to lying, and the context window is quite small so it doesn't remember any of the previous conversations, and reading some other user posts here and adding to my own experience, these bots have several levels, some will only respond to messages with a generic sales pitch, some will actively monitor subscriber online status and then message, some may message if you interact with any content on the page and so on, I don't think there are many actual living people left on there chatting, I mean human chatters of the past, not even the owner of the account
and I'm not talking about Willow here in particular, seems to be a general trend
if you look at the OF api, then you see they gather quite a lot of data, a lot more than what you expect from such a bare UI a normal user can see, and creator account probably has access to at least some of it that might be useful to increasing interaction and sales, and all that can be done in just a browser extension using JS, no need for anything especially fancy, so even a moderately experienced software designer, of whom there are plenty unemployed now, will have no problem creating half decent bots for this quite quickly using AI
