IPRental
Thank you!
Like I said, it closed down sometimes in 2014? I can't remember the exact date. I started using it in 2011 when I needed access to most sites that were blocked from Pakistan (I was living and working there for two years). It was American, and their main service was to provide rotating IPs to users from something like a million residential IPs based out of North America (including Canada). It was popular because it was free to residents of some countries - Iran and North Korea at first, and then they gave open access to more countries during the Arab Spring. I recall TOR being extremely slow in those days, barely quicker than most VPNs and proxies, IPrental didn't seem to cut down on bandwidth. Since they seemed to refresh the IP pool quickly, it got by most blacklists easily too. They used a form of tunneling, but I won't remember the exact tech.
