Like anything else, there is a variety of people with different motivations being on SA. What originally attracted me to it was everyone knows an arrangement leads to sex. The messaging before meeting allowed me to get an idea of their personality and see more photos. With escorts, it's basically you decide off of a static website, or observing a twitter exchange, or from a board like MERB. It is not direct. After awhile patterns on seeking emerge to see fake profiles (e.g. mostly Asian) or women who are likely LL, or just DTF, which is ok, but is not what I am usually looking for. I have not seen any regular escorts in Montreal SA, but have seen Toronto escorts on seeking. BTW, they charge the same rate, just more flexible on the timing and you get to see their pics and a better exchange of messages, albeit, they still get right to the point LOL
