I wouldn't trust it. Though you you can honestly lie and mis-promote yourself on any site really, for some reason GAG strikes me as pretty sketchy. For dating and finding dates, stick to websites made for that. GAG is a Question/Answer forum, and its interface wasn't made for hooking up with guys/girls.
Not to mention, half of the male accounts on here are just one of multiple of the same person's, who send the same message to anything with a pulse, haha. I've gotten doubles of the same specific message (sometimes within the same hour) from multiple accounts that have the same profile picture but the location changed. I have an old (unused) account on here where some guy sent me a come-on about "driving a truck in dirt or snow"... and without knowing it was me, he sent me the same message again on this account, haha. The GAG community (though obviously not everybody on here) is very sketchy, and I wouldn't trust it.
Well considering most guys on here are completley insecure I would say no. Just look at what the avarage males questions are about on this site and it might give you a idea. Saying that I was very close to meeting a chick from gag once but it ended up being terrible timing for both of us and we both met someone. But we still get along great.
Is this your way of asking me on date? Jk It's as safe as any other website. There are always associated risk with dating people online or offline. Most people on here are taken and are just looking for advice.
