Need Help with Old PVA / PVA Zone Accounts

I purchased a bunch of Double Verified Accounts from Old PVA and PVA Zone recently in hopes to kick start some subscribers to a couple of channels I want to build. My subs with these accounts keep dropping off. When I login to the accounts it shows I am subscribed to the channel, but after subbing over 30 times my channels only show 6 subs. At one point they showed as high as 24 subs but within a few hours most of them were dropped off.

I created new channels with each of the accounts I purchased and subbed again and the same thing happened. My channels have videos 3-5 minutes in length. I've watched the videos, liked, scrolled down and left comments to show engagement and still nothing. I've also posted the videos on facebook and reddit, clicked from there and subscribed and still nothing.

Any advice would be appreciated. I'm starting to think Old PVA and PVA Zone accounts are just junk.

Are you using different ip's from different platform?

Bump. Please help. I’ve used VPN for some, my same IP for others. I’ve also created brand accounts per gmail. Nothing seems to work.
