person text me wanted my paypal email so they could purchase an item from me off of Kijiji.

paypal scam!!!!

I really appreciate this forum, I have a car posted on kijiji and have been receiving all kinds of interest from scam artists, so now if I receive a call or a text from a phone number I check it out here on this forum.  Received a text from this number inquiring about my car for sale, never responded of course, but if I was an innocent victim, I wonder what kind of scam they are trying to pull off?
