The popularization of the Internet might be twofold perceived. Firstly, as an undisputed benefit. More and more people get an unrestrained access to enormous volumes of knowledge, get a possibility of contacting with other users from all over the World, and – why not? – get another great entertainment tool. On the other hand, uncontrolled Internet expansion might be ambiguously used, sometimes not in a way we’d like to. Thereupon, Web filtering tools are more and more popular. As long as more and more web content is used for controversial tasks (especially hidden advertising), anti spam becomes the only method for selecting the websites. Even though visiting only trusted websites might be somehow effective, it doesn’t protect user against pop-up advertisements, automatic links and other tools. Often, only a one ‘typo’ is enough to open porno site instead of a news portal. Do you really want to let advertisers decide how you use the Internet? Is it fair, that others constrain you to watch what you do not really want to? Think about your children. Do you want them also to be influenced by advertisers? Stop these pathologic practices – invest in Url filtering and enjoy the safe Internet. Now it’s really possible.
