I know a friend of a friend who had a platonic sugar daddy - this is extremely rare. From what I’ve heard from sex worker friends, the most common thing they want is companionship (followed by sex, and then nonsexual kink activities), so you would still have to provide that even if you’re not going to have sex. You can’t expect money for nothing, but sex is not the only thing being asked for here. I can’t speak to getting banned or not, but if you are not willing to have sex or indulge in any kinks you will realistically be looking for an absurdly tiny pool of sugar daddies, while sifting through tons of typical potential clients who do expect sex and/or kink, and plenty of scams on top of that.
