Seen a couple of forums wind up doing experiments along the lines of posting the same profile on a dating site once with a hot photo and once with a not hot photo.
Then they tried the hot photo with a good profile and a bad profile (like they wrote anything).
Apparently you can write any old nonsense and claim your favourite hobby is clogging puppies to death as long as you have hot photos.
Yeah, this is actually true.
I got a bit wound up on my POF profile so I simply changed the pictures to an obscure model, I even put in my profile "My pictures are fake" hidden in the wall of text about myself, and still I was getting so many messages that in three days my inbox was full. Funnily enough some of the women who I had messaged before and whom had either deleted my message without viewing it or replied with "Sorry, I don't date fat people" or "you are not good enough you ugly ....." were now messaging me flirty chat up lines.
Some actually read the profile and messaged me saying they found it funny and that I had a nice ironic sense of humor.
This is how I came to the conclusion that when it comes to online dating it really is all about looks.
