Personally, I’d say never reveal your face on the internet unless you want everyone to know what you look like. It doesn’t matter if one of your friends did it or some YouTuber does it, it matters if you want to do it. Even then I probably wouldn’t. I’ve done it once accidentally on YT (only a few people saw it so thank god) and once here and I deleted it. To this day I think it was the one of the worst mistakes I’ve ever done because I don’t want people to know or remember my face. Hopefully they’ve all forgotten by now but I doubt it.
However it’s not for me to try to convince you to do it or not. That’s just my preference. Whatever you decide to do, face reveal or not, it’s your choice.
