Section 1030(a)(4) covers computer fraud and any use of a computer to commit a fraud or to further it falls under this section. But it makes one important exception, it specifically exempts frauds where the only thing of value that was obtained was the use of the computer itself and where the value of such use is not more then $5000 in any one year period. Originally, CFAA did not consider trespass a crime, but Congress recognized that computer use has value of its own but nonetheless included the $5000 threshold to prevent turning every case of trespass into a fraud felony.
