There is considerable risk in using open proxies from unknown sources. Many of these are called free proxies hacker pots. They are there waiting to fall into their trap so they can steal your information and the plant bots from your computer. Once a robot is sowing the hacker has control of his machine and can steal the credit cards, attack Web sites and send tons of spam, all from your IP address. Some of the free agents are headed by people to make money. No nothing wrong with that, in principle. But the best here is that you get a performance full of ads, not the actual speed to it. The amount of money the owner can do with a few clicks of advertising is really just pennies. Many of these homeowners to supplement their income by recording all keystrokes that make and sell your personal information to advertising companies. Since there is no way of knowing what the owner is actually doing is necessary to assume the worst is true.
