wait wait wait, so you get a new IP every time cuz it's AOL dialup? ohhhh I just kinda delete dialup from my thinking process because nobody in their right mind has it lol. Yeah you can very easily get someone else's IP that way. If you have high speed, they still do recycle IPs but they only change like once a year tops so you're stuck

Any proxy should work though, I don't know why they aren't. Id suggest stopping at the library then and registering there. Or do it at a school or your parents work or whatever, just go somewhere else and register.
