Fully 71 percent of e-mail users use filters offered by their e-mail provider or employer to block spam. Users also report less exposure to pornographic spam, which to many people is the most offensive type of unsolicited e-mail. Spam has not become a significant deterrent to the use of e-mail, as some observers speculated it might when unsolicited e-mail first began flooding users' inboxes several years ago. But it continues to degrade the integrity of e-mail.
Some 55 percent of e-mail users say they have lost trust in e-mail because of spam.
