I afraid Patagonia is correct here.
It sounds like you have walked into something you think you understand. But have only experienced through porn.
I have a really good link explaining they D/s relationship without going into it too
technically.
The Mistress of an establishment, online or otherwise is there to protect her clients, that's why you have found yourself blacklisted.
As you seem to have shown a profound mis understanding of the basic etiquette of the social circle you have entered.

As a 'collared' sub, I can assure you we see enough of your type of if you mis understanding to last lifetimes, but I am always willing to provide educational source material for those who seek to educate themselves.
For example just because I am a sub doesn't mean I am open to all and any sexual advances, nor does it mean I am there to take abuse from anyone who fancies a turn.
Every sub is as different as each Dom, and requires very specific and individual care.
And that by the way is the role of a Dom, to be responsible for the physical and emotional well being of his sub. Not to use as a lashing post for his own frustrations.
Perhaps you should assess your needs, what your looking for and what you expect.
If require short and concise intro into the relationship between a Dom and their sub I would be more than happy to provide a link.
Otherwise do take the time to investigate further if you feel so inclined.
All the best, take care.
