I watch a lot of the popular YouTubers, and I've noticed there is this one guy who is always there on those videos. And by that I mean that he comments something about visiting his channel, gets it to top comment, and then once it has been marked as spam (or about 5 hours later) he will go on a different account and say something about how its the first channel that spammed that they actually liked, something cheesy like that. Then he will get that to top comment as well, and tons of subscribers due to the fact that it looks like someone else actually liked it. I have been using TubeToolBox and it gets me about 20 subs a day, but I would much prefer to be able to post comments like this and gain a lot of subs. Today so far he's gained over 400 subscribers... If you don't understand what I mean, this is what it looks like. http://i.imgur.com/LXCgLQY.png So what is he using to do this and where can I get/buy it?
