Wtf! Who could fool people would sell his id and selfie in internet world? This is crazy, OP will surely sold the identity to bad guys online or he might use it in illegal ways on darknet thats why we should not sell our id if you dont want to go on jail for unknown reason.
Well some people will even sell the own sould just for a few cents...
The seller can and will get in very serious trouble because he have no idea what op will use them for
