We just had someone with what appeared to be a legit SASS number and history with a year of posts, try to sell a SAA and a Python twice to 4 different people who all sent checks. Luckily all the checks were able to be cancelled when the whole thing just didnt smell right. Perhaps when an add is posted would it be possible that the persons SASS number and all relevant information be confirmed. I am not sure whose job that may fall on. Be wary folks
