I will be in a small minority on this, but I like a long profiles and am happy to sit and read them. As long as it isn't just drivel, the more information an escort can provide the better.
For example, to my mind, it is no good an escort stating that she likes roleplay, without giving some idea of scenarios/roles she enjoys and any costumes available. This provides something with which to work and a chance for some inspiration/originality.
However, long profiles do need to be properly organised (tabs, paragraphs, etc.) so that they can be easily navigated.
