Not necessarily. Whether or not, as well as when, to pursue a license violation is completely up to the license holder's discretion (at least in the USA). Not receiving a notification could be indicative of any of the following:
 * 1) It is not a license violation
 * 2) They license holder has decided not to pursue the violation at this time (but may still do so at a later date)
