How can i avoid youtube flagging system?

Even if i change my ip / change my HWID and install a older version of chrome or use another browser and of course, new youtube pva account, my comments still getting flagged. I can only post 10-20 posts a day then i get ghosted, even if i change all of that ,i still get ghosted.

Any way around this?
Of course, if i post on another computer, i can post another 10-20 posts just fine...

How does youtube detects your machine?
