Sure. As a client I am also doomed to Rentmen. Their offer is way bigger than the smaller websites' and the service is technically better.
However, that fact does not mean I cannot or should not support alternatives. You can also publish for free in Mintboys, as you pay only for the premium advertising. You are a well established and already popular escort. You do not need an alternative outlet. Perhaps, it is even against your business' convenience that alternative websites come up widening the offer and posting better prices for similar services.
My support for websites like Mintboys and Friendboy or like Traviati in Argentina is not coming (only) from pure altruism. It is in my interest as a client. I want a more diverse market and I want more competition to keep the prices at a reasonable level.
My apologies for derailing the thread.
