Their attitude completely stinks. It doesn't matter if it's escorts, porn stars, "models" or dommes. I have contacted dozens of them over the years, and only like 3 in every 50 you contact are decent and give a good, down to earth first impression. The rest are just totally odd or arrogant.
I'll be courteous and not name people. I could. But these ones who do BDSM have the most sad attitude. You cannot message them or anything, without fear of some type of nasty reaction. Very cold and awkward. Then they ironically complain about being ignored on X. Or moan about their business drying up.
You would have to be higher than a kite or pretty worthless to simp for them, knowing they don't give a crap about you.
Just full of themselves and putting profit over politeness. This carry on can invariably involve being scammed, ghosted, blackballed, and mistreated. Then you just feel dumb for having bothered.
