If you don't know already, TubeToolBox is basically a piece of software that lets you scrape all the channels of commenters on youtube videos of a specific keyword, specific users' subscribers etc and then mass PM and friend request them. It used to also be able to mass comment on people's walls but obviously that doesn't really exist anymore. However, YouTube has pretty much wiped out the whole social side of the site over the past year and so I was just wondering if anyone is still using it and whether you think it'd be a worthwhile investment? I'd be doing it to promote my legit videos more than for marketing purposes. It costs $49.95 for three months or $99.95 for a year or $149.95 for a lifetime subscription. Thanks!
