The spam, as we know, happens different types. And each of us daily, entering into ICQ or using service of "VKontakte", checking mail, unsubscribing in logs and diaries, faces his numerous manifestations. For what the spam today is used? Not only for advance and bright, being remembered, annoying "public relations" of the product, but also and for an anti-advertizing of goods and production of competitors.
So, the spam happens several types. And today on равне with happiness letters which come to many Internet users, quite often we become witnesses of a spam in logs. Such spam is called refspamy.
