What if I hide the URL with another word or picture, and make someone click into it?
By the way, according to WiKi:
“Entrapment is the act of a law enforcement agent in inducing a person to commit an offence which the person would not have, or was unlikely to have, otherwise committed.”
Good point. Identity thieves use this trick all the time to have you go to a site (their site) to confirm personal info usually about credit cards or bank accounts. Someone could send you a "patriotic site" or a Clinton or Obama joke site and it could turn out to be the "illegal to click on" FBI site.
