We would have been free of thousands of unwanted information. Information that are filling our brains, using our neurons – what for? To make money. We need to understand that there are two main goals of spam. First one is related to people who treats spam as hobby and as a mission to make the servers of big corporations busy or even jammed. Another one is less dangerous but for sure much more annoying than first one. Why? Because second is connected with something that people in twenty first century are pretty sick off. What could it be? If you thought about advertisement or marketing than you surely know that spam is also a tool in hands of people which are trying to get in to our head and house through every available and possible channel with super hot news about another toothbrush going on the market that will whiten your tooth better than any other. How to defend against both types? Installation of spam filter might help but in my opinion people have circled around themselves in the internet borders which they very rarely cross. That is why web filter is efficient and helpful. Thanks to url filter we can keep our small garden in the internet free of any undesired trash like spam or even spyware.
