I don’t want my gmail account permanently because of a comment I made on YouTube, nor do I think that should be commonplace. I’m not sure what the best solution is though.

I once worked for a server hosting company that had a few different “branches”. It was pretty common to see different types of misuse or abuse. Whether it be credit card theft, hosting copyrighted content, or hosting phishing sites. I would go out of my way to monitor for and ban all associated accounts at all branches of the company. Not because I wanted to ban their personal accounts, but because 99% of the time those associated accounts would immediately engage in the same behavior. You can sit there all day playing whack-a-mole, or you can exterminate the mole.
