So I was on Grindr last month and I messaged this guy who I've occasionally talked to because he lives the closest to me. We were chatting and he wanted to exchange dick pics. So I sent him mine and he said it was small so he sent me his and I said oh it doesn't look much bigger than mine. Well, he went off on me asking what the f is wrong with me. Then he threatened me telling me if I don't take it back that he's going to come around my neighborhood and tell everyone about me. I don't know what he meant so I blocked him right away and reported him and Grindr got back to me and said that they had temporarily banned his account. Now he knows what I look like and I know what he looks like and I see him walking alongside my road occasionally. Should I be worried in any way?
