OP, it sounds like you don't have much experience buying ads on the platform or really any understanding of FB's opsec.
FB looks for signals that indicate accounts could be fraudulent. It goes way deeper than IP, useragent, browser, etc. You mentioned you could make a bunch of accounts because Linux Parrot... Using that OS would almost guarantee to throw a red flag right away. Maybe I'm missing something though as I don't know anything about that OS other than what I just Googled.
If you're really going to try something like this, you should spend some time researching how FB finds the bad actors. You won't be able to pull this off without a massive headache. You'll probably inadvertently get your real account flagged as well and then you'll be forced to always circumvent systems, even for WH stuff. That's not a fun position to be in, especially if you're just getting into ad buying.
Nobody who is operating a high level with FB ads does this stuff, because there's literally no reason to. Just learn how to buy ads, practice, learn all the nuances of ads policy/compliance, and then you'll make real money. Good luck either way though!
