FUCK !  there is no way to add NSFW label when posting to communities.

@Stuart Bowman you are sleeping on the job !

i am bombarding my timeline with highly questionable porn and can't put a warning label on it because i am posting it to the Community which doesn't seem to have that option.

HELP ! ! ! 

 This would be good, as your feed is the one I’m using to debug / code filters for questionable content, you produce lots of stuff people don’t want to see.  

 With next update there will be a way to exclude community posts from your main timeline 

 great news.  it should be the default IMO.
