I agree this problem has always existed. Brutal rules always demotivate people. No one has yet found a compromise. And yet I remain with the fact that cluttering up screenshots should be prohibited. No need to ban for this, but we don’t need garbage dumps.
I am in favor of tightening this rule even more. I've been an active editor of The Simpsons wiki in two languages and I can tell you that characters' and episodes' pages are 1,000-screenshot dumps and will take many times longer to view than the episode itself. At the same time, screenshots are always low-quality and often duplicated. This is trash. In my opinion, there should be a rule that generally prohibits adding more than 30 screenshots per episode. No one just ever needs more.
