Back when I was in online dating (I got married in 2010, so it has been a very long time), this is how it seemed to work in the hetero arena:

• Women (by which I mean, legitimate accounts from women who were actually looking for dates): Get 1,000,000 messages, approximately 999,900 of which are dick pics.
• Men: See 1,000,000 ads, of which about 3 are legitimate people looking for dates.

So, both could be true in relation to the image.

I remember a guy once telling me that basically you have to respond to EVERY AD and hope something sticks. I never did that, and I felt bad for what the women must have had to deal with when I heard that. I had very limited success - dates with, at most, two or three women, and none of those really went anywhere. I ended up marrying someone from work instead.
