Findquestpr wants to JV park my domains

Just got an email from a guy named Devan, saying he's written a new script and would like to JV park my domains, split 50/50. I asked him what all he wants, because hey, I'm actually interested in using some of my domains that aren't going to be doing anything.

Just did a little research, seems he's been spamming a lot of people for this deal through a godaddy sponsorship, an that findquest dot con is a search engine.

What to look out for? I mean how do these spammers work? Try to take over ownership, or actually park my domain?
