It is known that the word “spam", which has not only firmly entered the everyday life of a modern person, but also pretty much became boring to the vast majority of network users, became familiar to mankind long before the advent of Internet technologies. In the mid-30s of the last century, spam was not called annoying emails at all, but … expired canned minced meat. Trying to sell products left after the Second World War and not particularly fresh, the American company Hormel Foods decided to resort to a rather original method: an advertisement for canned food called Spam filled literally the entire space: from shop windows to public transport, which caused a corresponding reaction from the American public.. If we talk about today’s spam, then in the sense in which we talk about it today, The term first appeared in 1986. It was then that a certain Dave Rhodes, who promoted another financial pyramid, sent out a huge number of advertising letters with the headline "Make a lot of money", which caused many people to associate with the ill-fated canned goods promoted exactly half a century ago, and were also called spam by analogy. So, today the word "spam" has a generally accepted meaning: this is how we call intrusive advertising mailing (most often electronic) to those addressees who do not need this information and do not want to receive it. According to statistics, the proportion of spam in modern mail traffic is about 80%, which makes the public seriously think about the extent of this problem and how to deal with such a phenomenon as spamming. Today, the fight against spam and spammers in many countries of the world is quite active. In the United States, for example, the federal Can-Spam Act has been in place for more than seven years, bringing legal liability not just to individuals, but to entire companies as well. It should be noted that some of these attempts are successful (one of the clearest examples of this is the satisfied $711 million lawsuit filed by the world-famous Facebook social network against American citizen Sanford Wallace, who was involved in spamming on this site). At the moment, the only country where spam is legal is Bulgaria.
