Tinder: Chicago Anonymous Profiles?

I’m currently interning in the Chicago area, and I’m also on Tinder.
I have a profile with pictures and a description. But I’ve noticed that there are an unusually high amount of anonymous profiles. I came from Florida.

Does anybody know why that is?
I have theories:
1. They don’t want people they work with to know that they’re on tinder?
2. They’re unattractive?
3. They’re in a relationship and just checking guys out?

Does anyone have a good explanation?
I was also on Tinder in DC, and I don’t think there were that many anonymous people. Although, I can’t remember.
