so let's say, I have 3-4 channels in kids niche, and they all dead. by dead I mean, in around 2017 there was an update and youtube demonetized all my channels, varying from 1mln to 3mln subs. I was on nerves those days and got mad and deleted all the content from the channel. started other channels and went along with them. from time to time, I'm trying to upload some videos, but not seriously, like 2-3 videos, and again focus back to my main channel. if I upload some content now, it gets around 200-500 views long format, is it possible to revive those channels back? I mean algorithmically, is it possible that their history have had been reset? It's okay if I need to work on those channels as if they are new, I'm just curious if they are not under shadowban or something.
