Profile verification can be done by requiring a photo with a randomly generated code that must be hand written with the date. No reason to require users to share the ID which require more security.
I would say you should require the photo to be taken with the grindr app to be uploaded to help prevent photoshopped images.
The only issue is that Grindr only allows you to have one photo and you can only verify to one photo so anytime someone changes it you have to reverify.
