There are many ways to spot a fake finsub/payslave/pig. They try to fool us but their ways to do so is beyond worthless.
One easy way to spot your ordinary vanilla male who’s out looking to sext and get nudes, is that they get offended when denied. First second you’re the most beautiful woman in the world. They want to be your slave (even tho they have no idea what financial domination is most of the time) and the second you tell them you’re not interested or that you don’t sext or send nudes – you’re an ugly whore.
Your true sub would’ve been sad and apologize for thinking such a thing. He/she KNOWS they’re inferior and that you’re right. If you’re not interested in them then it’s their fucking fault and all they can really do is plea for another chance and prove their worth in money instead.
