I received a message from a guy last night that I responded to today, and we exchanged a few messages. He was very attractive and seemed nice, but you know that gut feeling you have when something doesn't seem right, but you can't place it? That's what I had with him, so I decided to use reverse image search on his pictures and see if anything popped up. I use it sometimes when I have those gut feelings and think a guy might be using fake pics. No fake pics here.
Instead, his picture shows up on a site that lists online sexual predators! It's not an official sex offender registry, but a site that others use to submit names and pics of guys that are online sexual predators. I'm not saying necessarily that every guy listed on there is guilty since the site puts anyone's pic/name up that someone else submits (from what I can tell reading the FAQ). But, it was enough for me to cut off contact completely.
I know everyone knows to be careful, but I guess this is another reason why you should trust your gut if something feels off.
