A proxy is something that allows many people on the internet to view websites like Facebook and myspace if they have been banned. Now typically you shouldn't be sometimes in trouble and banned at these websites but it happens sometimes, or you may also just like having the privacy that you get from using a proxy. Nobody will be able to track your IP address when you're using a proxy because you are not actually connecting to the server of the website you're just viewing the pages over the internet.
There are thousands if not millions of people who need to use proxies due to being banned from websites but the number one reason I believe proxies are used happens because many schools block websites but with a proxy you'd be able to access anything. Schools hate proxies but you can't really block or ban every proxy which is why they are so popular. Many proxies get banned from lists or they shutdown and then a new proxy comes that is just as good and can offer the same service. 1337x.st
To find out which proxy servers you can use to view websites you should consult aid from a proxy list which lists numerous of the top proxy websites online. These lists typically need to update very often because proxies are changing all the time, it's hard to maintain with what proxies will work and what ones aren't, but then with a proxy list you can find the updated proxies to use at all times whenever you need to understand.
A proxy list is very valuable to people because without them you wouldn't know which proxies were open and which are power down. Proxies change every week and some closed overnight due to unexplainable reasons which is why proxy lists need to be updated usually and why they are so important to us proxy surfers.
