Hello, I have been doing research on YouTube video upload, traffic generation and YouTube commenting. The one that caught my attention is "YouTube commenting". I saw some videos, in the comment section of the video I saw comment with huge amount of likes and the comments have tons of comment but when I tried to reply I could not then I ask a question from an Indian friend he said those guys are making tons of money with that and that he does not know how to do that. I will attach image of what I am talking about. If anyone know how please share with me privately.
