Completely agree! I understand that people aren't comfortable with putting them up, and I respect them for it! it just makes me nervous about answering some, sometimes... :/
I agree too Darling (great name!

)
I always feel a little bit of a twinge of something like guilt when I ignore a photoless profile, but it makes me a little bit apprehensive when someone messages me without a photo. Its like they're hiding. I understand that people may be shy, or cautious, or whatnot, but I do choose to be cautious as well, in not answering or contacting them. My own safety comes first.
I actually do judge a person by their photo though. If someone looks grouchy in a photo they've posted on a dating site, where they want to make a good impression, I steer clear of them. I look for kind eyes. Regardless of what their appearance is, if they have a great smile I will respond. I'm very attracted to a good sense of humour, and to those who appreciate a good sense of humour. I have this idea that they're usually light hearted and open to others. Lovely people.
