i think it is to some extent up to us to regulate this, which is good and bad. I would also be interested in other news instances, but it seems like all of them have some amount of garbage linked sources. I just try to call it out in the comments so other people will double check on the validity of the headline as well. Community moderation may be better than a single moderator with the power of 'censoring' the whole instance. Also, by writing really long paragraphs like this maybe we can draw peoples eyes to the fact that our up/down votes also regulate what links/sources get traction and that catchy headlines may not be enough to warrant a vote up.
