Not knowing the truth is not a defence in a court of law. Even if the minor lied, he is still a minor and the adult will be the one who is held responsible.
Minors lying about their age has happened time and time again in the past, long before the Internet, and many adults paid the consequences. Now the anonymity makes it much easier for adults to be 'sucked in' by minors, and it happens much more frequently.
That doesn't make you less innocent. You're just as guilty and you can be held responsible. Cutting all ties doesn't fix it.
I do not know if that is true. A friend of mine met someone on a gay dating site and went out with him a few times. He eventually got a call from the police because the kid was underage. The police told him they couldn't do anything because he met the kid through a site where you are supposed to be 18 to access the site. So my friend must have assumed the kid was at least 18, they did however warn him to be careful in the future.
