to all the vpn and mobile proxy questions, I used a vpn for some pcs and just used the IP on a few hetzner and AWS servers I had for other botting stuffs and a bunch of gmails, no mobile proxies were used. I ran the auto like extention for days. If you go to a profile and click play all on a channel, you can get all the videos into one giant playlist and let the chrome plugin play and like everything. VPN each time should be enough, I used chrome browser for watching with no incognito but im sure that would help.
I would also recommend microworkers and ytmonster for likes and engagement if you had a budget.
using SMM services, like subs and views, ive seen channels get shadowbanned for that so I did none of that kind of boosting, Just
shorts in a playlist and auto liked untill it got into recommended rotatation and it just took off.
