Generally, advertising for an adult, porno-graphic website that is sent to an email address does not violate federal law or the current laws of most states. In some states it may be a violation of law if the sender knows the recipient is under the age of 18. Such advertising can be reported to your service provider and, if known, the service provider of the originator. It can also be reported to your state and federal legislators, so they can be made aware of the extent of the problem.
