Whenever people are surfing websites, their ip address is being logged. Even the most simple logs are able to show you which IP on which time visited which website. That's where proxy sites come in handy, when people use proxy websites, not their IP is logged but the IP of the proxy website. Even if you have nothing to hide, you should proxies, just for privacy reasons.

Proxy sites are websites who allow visitors to surf to blocked pages or banned pages. For example on schools, colleges or workplaces Youtube might be blocked. When using proxy sites, you have still the possibility to surf to Youtube through the proxy. If you are blocked from one of the websites you visit daily, you can use one of these proxies listed on the right side of this page.
