server proxy account

Can I have multiple accounts on a website while using the same computer if i use an anonymous proxy server?
I was wondering if I could get multiple accounts for a website if i sign up while using an anonymous proxy server. Or should I create multiple accounts on my computer and just sign up while I am signed into those accounts? Or would resetting my ip every time i want to sign up make me look like different people? Will they know if it is me if I do either of these methods or will they think they are different people? Which is the most effective/efficient/secretive/safest way to do this or is there a better way???
Proxies are dangerous and near worthless.
Even if you do get a proxy to work for a bit what do you get? A lot of these are hacker pots designed to either steal your information or plant bots on your computer that they can use. They use them to hide their identity by working through your computer and its internet connection. The recent Facebook and Twitter DDOS attacks that took down their entire networks is a classic example of what people using proxies and getting infected enables.
Even if it’s not a hacker pot it’s probably loaded with advertisements as that’s how the owner is making money. In either case the owner has no incentive to provide fast response or high bandwidth. The owner of the proxy is using you and delivering very little back to you. In fact, there is a good chance they are data mining you so they can sell your information to advertisers who want to target their ads. In most cases advanced web site features won’t work and only basic access will be available anyway.
