Just don't advertise. I don't see anything wrong with it. Just remember to follow the rules. You can tell a bit about yourself and what you do. Heck you can explain in detail and it's fine. I Just don't allow advertising outside the designated YT and Twitch threads. You can still explain in greater detail.
That means no outbound links to YT, Twitch, Or other websites you personally own. It's as simple as that. No FB, Twitter, or Social Media advertising either. You can still tell people about the things you do.
