There is a huge thread over at Poser Pros concerning SA called "Do I look shady to you?"  A most unpleasant incident, the upshot of which is some people, including myself, have become wary to the point of not buying and/or not using models of theirs. The items were legitimately purchased but not at their site -- I got mine from Daz  -- and they demanded somebody's proof of purchase with no good reason or even good manners. You can read the whole story at PP ... which makes me think this "do not discuss our models in other forums" policy of theirs is how they want to deal with all the well deserved criticism they got for practically calling people thieves without any evidence of the sort.
