i'm thinking this should work, you can't get a lot with one computer, by using a proxy, because you have to keep the video open for more than 30 seconds (from what i've read, preferably half the time of the video), but it should work.
if the video is 2 minutes, and you have a program that switches your ip every 1 minute, you can use firefox reloadevery to reload the page every 1 minute, and you should get an individual view, that's 60 views an hour, 1440 views a day from 1 computer, now if you had 3 computers that should be 4320 views a day.
but you'll need a good software to switch proxies with. you can't use something like tor, because it's too slow, it would take 5 minutes per view with something like tor.
or well lets say you do use tor which is slow as hell, and you open a tab over 10 different pages, that's 60/5 = 12 x an hour , 12 x 10 = 120, so 120 views an hour x24 = 2880 a day, but to get 10 views in 5 minutes with tor, would seem like quite the difficult task, but it would seem doable with a killer connection and some decent proxies.
but i'm not sure if this will still work, it's 3 in the morning and i'm pretty tipsy, i used to do 1000-3000 views a day with tor but that was in 2008, i haven't had anything to do with tor or youtube since, i'm just trying to figure out how to get a lot of views myself right now.
i know a lot of people cheat up to 50,000 views a day, but i haven't figured out how to do it yet, and nobody here seems to know neither.
if anybody here could sell me garanteed 30,000 views a day, i would buy it.
