One tactic I did back in the day was I used Jarvee to scrape videos with certain tags And left a comment on their channel. It was for a few rappers, so I targeted anybody that posted a video with the tag "Beatmaker" and complimented their beat and told them to hit up the artist on Instagram. It worked really well and didn't get flagged, but I had to do a certain amount per day and had to create comments that had really good syntax. I think the automated tool now is SuSocial. This then got us views, comments, and dm's with free beats. Or the more text like this, you can set up different ways you can get views instead of buying fake ones.
