Since you failed to post the "google definition", here's the one I get at the top when googling "spam definition" > Unsolicited e-mail, often of a commercial nature, sent indiscriminately to multiple mailing lists, individuals, or newsgroups; junk e-mail. Note, "unsolicited" is the first word and "irrelevant" does not appear anywhere and there is no discussion of the utility of the message to the recipient.
