Is there any reasonable explanation for why someone doesn’t verify their profile?

I’ve been noticing I get likes from profiles that aren’t verified and in the past have always just immediately chosen not to match them. Honestly, the profiles aren’t pictures of someone good looking enough to be a catfish. So I’m just wondering why people choose not to verify their profile if they are the person in the pics. I want to add these aren’t profiles that say “new here” or anything like that either.
