Spam is not a technological issue, but a social one.

"Although it was in fact, it was not resolved, in some cases it made it worse," said Rebecca Wettemann, VP of Nucleus Research. "Spam is no longer just a technology problem - it's a problem that we should be attacking with more than just technology."

Loosely translated

Most companies use filtering technology to solve spam problems, in most cases this only worsens the situation. Spam is no longer a technological problem - it is a problem that must be solved by other methods.

Recent trends in this direction, which are worth thinking about.
- Confronting botnets (solving antivirus problem, closing vulnerabilities in the OS, recognizing and blocking traffic from such networks)
- The social component. Now social networks have already achieved this scope that allows you to build models of protection against spam, when most of the contacts are located within the social network. For example,
Microsoft has been working in this direction for a long time and is regularly looking for employees in this area. Google wants to close the email traffic inside gmail.com. The main problem is that there are many networks and there are people who are not in any of them.

Although the construction of such services will open the way to personal theft. A hijacked account on a social network (or form a fake one) will allow you to send spam, viruses, or tamper with the trust of such a person through her own contacts. Facebook, LinkedIn and MySpace users have already encountered such problems.
