i'd say drop hidemyass as all of there ip's are blacklisted. Go with a private proxy company like squidproxies(they have a thread here with a discount) and use that. They also allow you to change the ip's once you start seeing that youtube or what ever is onto them and are banning your videos quickly. I've been using squidproxies for a while now and it has been good for me. Yes some videos do get deleted but thats just the way this shit is. Your biggest mistake here is using hidemyass and im sure of that. Hidemyass is being used by lots of SEO people, warez uploaders, carding rings, script kiddies, sqli scanners, mass defacers.......... Almost all big companys are blacklisting these ip's fast. So give a private proxy company a try and get yourself some fresh ip's that really havent been used much before and ONLY you are using them.
