Link Spammer Software

This guy is coming up on the first page of google for "cheap viagra" and is obviously using some kind of auto software for his backlinks as all of his backlinks are on comment pages and he has around 7000 of them. Anyone know what he might be using as it is working?

I cant post his link cuz I am new here but the is the guy with the YouTube channel:

youtube.com/user/ViagraCheapest1
