Understand Spam

Knowledge Sharing:
1.  The secret is not very obvious but it is repetition. The effect is not even in repetition itself but in repeating many times, huge number of times
2.  Organizing such long-term advertising campaigns companies have to take into account the percentage of instances when a viewer misses the program, changes the channel, turns off the sound or switch off the TV. This percentage is huge and in order to get the desired result commercials must be shown not just very often but infinitely often and everywhere.
3.  The goal of spam is to make you to consider its offer immediately so you either order the promoted product/service or at least visit the promoted web site.
4.  To make all this happen not once or twice but regularly, i. e. to guarantee a steady flow of clients for the advertised company, it is necessary to send spam letters to millions of people and to keep on sending those letter as often as possible.
5.  It would be no exaggeration to say that the work of a spammer is similar to that of a gold prospector - tons of sand are passing through his hands and he only gets some few grams of valuable gold. In fact, here is the main weakness of the whole idea of spam that has to be exploited in order to combat spam more effectively.
6.  The same can be applied to spam. Creating or choosing a spam filter it is not necessary to try to achieve 100% guarantee of detecting any spam message and in fact this is simply impossible. It is enough to use a filter that is capable of reducing the number of spam messages received by e-mail users to such an extent that spamming advertising campaigns become inefficient and unprofitable. And then, after a while, spam will become unattractive as an advertising tool and will be used less and less often.
