Sorry if this is dumb, but I'm new here. Also sorry if this has been asked before (Yes I did search). First of all, I must say that I was surprised to go to the "Proxy Lists" section and see posts containing huge lists of IPs and Port Numbers. Even though it was in the title. My question is, where do these proxies come from? Whose IPs are these? Also, what benefit do the people posting these lists get from posting them (ie, why not just keep them to themselves)? And why are the IPs in the lists willing to let random people use them as a proxy for free? Yes it's really cool and all that these lists are here, but it's surprising that there are so many free anonymous proxies out there. Thanks.
