Im scared - is all soliciting a crime?

First off you would have been violating the Terms of Service, which is different then violating the law. Second sure sounds to me like you DID violate the TOS. Third ignorance is no excuse, as they likely had you say from the start you agree to the TOS. If you choose not to READ the TOS that is YOUR fault and they can't go to your house and recite it to you before you start using their site. It is up to you to be responsible and read what you say you are agreeing to. If their TOS said you agree to dress up as an elephant when using the site then you would be expected to be dressed up as an elephant when using the site, as you agreed to do it(they wouldn't know unless it was some site that required you to use a webcam, but by point is to be outrageous to say you have to follow rules you say you will follow). They CAN fine you for not following the TOS, and you agreed to pay that fine when you agreed to the terms. That is how they get away with levying the fine basically.
