Sonic, you sound too desperate. In my own personal experience, the best way to get a dp girlfriend is playing hard to get.
When she compliments your awesome skills, act like you'd rather be shooting paintballs into her best friend... /ignore her, etc.
Also, you need an angle. All the girls at dpHarmony.com are looking to be matched with 55 points of true compatibility... skip that crap and find a way to stand out. For example, I'm the awkward Jewish guy, dp girls know me by that, and when they want awkward Jewish action, they know which server to join, you know? Others in the game... the pro game developer, the sexy-as-hell Texas IT admin, the mysterious Portlander, and the British "I'm 15 wink wink, looking for a hot 15y/o gurl" kid... these are all desirable dp boyfriends.
Good luck.
Oh, and be sure to get tested often for DNS/UDP stuff, girls can be nasty things.
