I had someone show up at my house looking for a Leolist SW a few years ago. The poor guy paid a deposit and the SW gave him my address. It took a bit of interrogation to find out what happened. Amazingly the SW was a BBW - not a cute one but a gross one. But I guess some guys are into that. I contacted her and scolded her. She did not reply but it did not happen again. This reinforced my approach to SWs - never pay a deposit, or share your real name and contact info, only have the cash you need on you, do not bring your phone, wallet, jewelry, FitBit, etc., park your car a block away, try not to let anyone see you enter the building, set up the appointment via e-mail, or text from a burner phone. Not a guarantee but this approach reduces the chance of getting ripped off or worse.
