So your considering using a proxy to a certain site to commit illegal activity, or just to fuck shit up on a site that has your ip addy banned? A double proxy is used when your too scared of getting caught, so you proxy your way into a proxy, then go to the site of your desire. Kindsa like the internet version of putting a condum over your condum. (as if anyone would even use one condum)
Vanessa: I'm gonna use a double proxy to watch some rape vids.
Me: your a dumbass
