I'm going to ghost a guy from tinder because he kept asking for selfies
Why are you on Tinder?  Do you not like sharing photos of yourself?
I just wanted to have some fun.
It is great to have fun and you are right to be careful. There are many weird people out there and it is okay to cut off contact with someone if they are being too demanding.
It's just a guy on tinder. I'm practically doing him a favor.
I'm glad that there are no hard feelings involved here, however, I don't know what the situation is.  Maybe this other person just likes seeing you smiling and having fun in your pictures.  If you have decided to move on, that's fine, it would be best to at least just let him know.
