I agree when you say that the idea of what is ’quality content’ is different for everybody.
YouTube videos can contain loads of quality information, but I’m against copy/pasting videos without bothering to give credit to the creator and at least spend a couple of minutes personalizing the post with a short intro, or a review or something like that.
It’s obvious the ‘beggers’ are the ones that irritate people the most. Those posts are spam without any doubt, whatever your definition of spam is. Actually that was not really the answer I was looking for, since it’s so obvious :-)
Those people will also not be affectief by spreading the message not to upvote spam, Since they don’t get any upvotes anyway
