I agree with keep things positive. but it does not make for a good rule. say now someone posts something about stage 20 loadshedding? will this get removed because its not about a sunny day and butterflies?
Perhaps the solution for that is to rather encourage Positive content to be created by the community. via a weekly event where you ask what made your week? or its Friday lets meme or stuff like that? Make post about stories about our heritage. Also remember you can champion a form of this, because what content you choose to supply the sub now will effect what future people will want to post.
IDK just adding to the mix here
You sir, are well informed.
