Autotrader needs to do something about this. I also contacted Gmail's abuse department. Received a group text message from this number to me and 9 other people:

"
Hi,is your Vehicle on Autotrader still for sale?Pls email me at. ([email protected])
it;s not a scam sir.
i;m a private buyer
just making inquiry
"

This text comes minutes after my post goes live on Autotrader. I am not even sure if my phone number is available to users on Autotrader. My, "Vehicle" is a very specific one, more specific than anyone would generalize with the world, "Vehicle". Who texts to ask to email? It's sad this  has been going on since at least November of last year and Autotrader, nor Google has shut them down.
