YouTube Channel Growth Q&A

I have recently entered into YouTube market, making money though ad-sense by create various types of videos.
As I'm quiet new to YouTube, I am still learning something new every day.
Recently, I have to know that we can actually buy permanent subscribers and watch time for the YouTube channel, you know black hat stuff. I search here in BHW community and sure enough there are people are doing this.
Curious enough, I search for the vendors and BAM!!!! found tons of it.
If you have used any of the vendors for your YouTube channel, which one would you recommend?
The choices are overwhelming and I want to start right.
Really appreciate it
Cheers,

I tend to go the more white hat way with YouTube, but purchasing subscribers won't do you any good unless you're looking to get monetized.
