I would mearly add 1k - 2k spread per a few days (3-4 days), and a few likes, all of which would seem as natural as possible.
After i reach that small number of views, i would quit using the services on that particular video, and let the video grow naturally.
The video is not monetized, because i would never try to risk my adsense account.
Is such a method safe to use? I would need a little advice, i used the search function, but i never found a proper disscusion on such a subject.
