Could someone who uses Github post this as an issue on the #Peertube git?

It would be great if NSFW was completely hidden by default, and had to be actively switched on in some way (similar to automatic safesearch on search engines).
NSFW content alienates potential new users, showing it by default (even blurred) is going to put people off sharing the site with others.
