@pixelfed there is some users who does not want to be in an environnement where NSFW content can be easily accessible.
Even if you are in a perfect world (we are’nt) where all users mark the right content as NSFW, some users will simply go elsewhere who is more ”family-safe”.
And a user might just avoid to open a site/app in a public place (example: in public transit) just to avoid the embarrassment of having NSFW stuff on the screen while kids could be around.
@pixelfed An other tricky thing: it’s opens the door to a moderation nightmare. Ex.: How old the subject on the photo is? Sometimes, it’s not easy to say.
And don’t be wrong, cauz the hosting provider (who might just not allow some type of NSFW content in it’s ToS) can suspend or terminate the account where the site is hosted on.
