Isn't it bollocks when a prossie states 'if you ask for X, Y or Z I'll block you'?
Just saw it on this profile with regards anal:https://www.adultwork.com/637168
If somebody inquires why not just say, 'no sorry, I don't provide that service.'
Bareback is the only exception, as I can understand why a prossie might not want to see a punter who seeks it.
Could you imagine a garage that doesn't service Renault's stating if you ever enquire about it you'll be blocked? Or a restaurant blocking you because you ask if they take reservations when they don't?
Of course, as has been mentioned numerous times, a prossie would do pretty badly running a business in the real world.
