I am not photogenic and seldom take selfies. I certainly don’t post them. The last time I looked in the mirror I was still me. You’ll just have to take my word.

All my photos are so incredibly attractive that I had a difficult time choosing one. Choosing more than one would just have taken too much time.

I don't like having my picture taken. I like posting it even less. One is enough. Please respect my desire for privacy.

I added extras only to max out my profile photo points, but I'm not looking for dating or serious relationships on here. If somebody you're actively talking to and considering dating has only one photo, ask them to post more!

Well, I'm who I am and only one photo. Will get around to more sometime. So there.

Those are definitely two of the markers. Add a low investment of time into completing the profile, answering questions, etc. and poor English skills... bingo!
