Fake people are always present, and the biggest problem of this app.
There’s the need of an AI system that verifies INTERNALLY the face of the person through the front camera for every photo added containing a face (this would be totally private and it would mantain privacy).
In this way if i ask for a facepic to anyone it will be shure it’s him. If the photo added didn’t contain a face this tool would not be used, but at least i would know it’s not a fake from his sending of a face picture, that surely would correspond to his real one.

Too difficult ? I don’t think so! Tindr has already implemented that.
