If you give them your email, they have part of what they want, they can sell it to some other spammer. Never answer to obvious GENERIC RESPONSES that do not have the specific name of what you have advertised and never give them your email. It is the same on Craig's list and other sites. I don't think Racing Junk or other sites can do much about it. I report all the ads that come from over seas, advertising software jobs and services as MISUSE of SITE, but don't know is they do anything about it. Those ads are always NEW MEMBERS.
