Why when people sign up for a dating site or a social networking site they don't upload a photo of themselves?

The most common reason is that they aren't confident in, or are outright ashamed of their appearance for one reason or another. Others, especially women, have had creeper/stalker issues or feel they get too much superficial attention if they have a photo up, and/or would just prefer to interact with people based on their personality without any influence of how attractive they are or aren't. That probably covers about 95% of them, and I can't think of much more that wouldn't fall under some variation of the above, besides fake profiles and/or someone posing to be the opposite sex for whatever reason.

Thats true. BTW Your handsome

They're married, they're famous...

but usually it's because they're ugly.

I do not know why.

lexxielicks, I am wondering about the photo in your own profile. Your profile says that your ethnicity is "White / Caucasian", but the photo in your profile shows a person who appears to me to be either Hispanic, Native American or racially mixed - something other than Caucasian. If I am seeing right, then can you explain your appearance in your own profile photo?

I apologize for asking in public, but your mail filter will not permit me to ask in private due to my age.

Or they could be hiding from the Alien Task Force.

Thanks for asking politely. I am mixed with Italian,white,and black.

Well, you are pretty no matter what your racial background is.

Thank you. You are a very nice person.

So why did you put down that you are Caucasian?


Sly

Thank you. You look great yourself. =)

They're either embarrassed about being on an online dating site, not confident in their looks, or seeing someone/married already. That covers most of them.

Well that's that, she gone!

Maybe they have received so many replies they have gone on a break by removing their photo temporarily.

Ugly? Perhaps 'malformed'...
but then again, who isn't in one way or another...

I took mine down because I was fed up of getting drooling men in my inbox saying how pretty I was. I'd rather be wanted for my personality. I don't care about whether I'm attractive or not. The right man will want to get to know me. I did have some up, but that was a while back.

because I'm Romulan and my ridges show

I don't have mine up because I'm not looking to meet any one. I'm just here for the forums. I don't feel the need to show what I look like for that.

that still doesn't always work.
