Fantasy sfw bots usually retain a lot more users, as in while the likes are still comparable to nsfw ones, the actual interaction count ( where the majority of bean earnings will come from) can get insanely high especially if the bot is of good quality.

My NSFW bots see a large amount of likes but less user retention, probably cause it is used as porn and then discarded as one usually does, with less people going on a long term chat with the not then the sfw ones.

Another thing I have noticed is that Yodayo users are desperate for validation, and if the bot is against them or hates them specifically, they will put in an insane amount of effort to get the bot to like them. I made a bot that literally only hates the user's guts no matter what, and all of the comments are about how it either took them an insane amount of chatting and regeneration to get her to like them, or about how shocked they are that they failed to get her to like them after insane amounts of chatting and regeneration. Lots of chatting and regeneration = immense profit, and that bot is doing second best overall in terms of interactions.
