Well good knowledge are not free!!
Did I got knowledge for free? So If you going in university tell them you dont pay you want for free ;!
But yes those kind of scams existing and I have ways to do background checks, but sure its not for free and not public info.
*please, dude.. don't make yourself look pathetic...a person who is really smart will not say that he is smart. there is writing saying; 'People who are smart will be more silent while stupid people will be noisier'.
