Good luck.
Still not shady if it helps others to learn Python. I don't have an issue that someone gets money for providing tutorials online. And maybe there's a reason why he doesn't want to find his name on Google.
Whois protection makes sense anyway, the amount of spam you get after registering a website is incredible. IMHO it's worth spending $2/yr for that service.
