Super Mario Maker stages continue to be removed without warning

Nintendo has been yanking Super Mario Maker stages that utilize glitches. That we know, but it seems they're also deleting other stages that don't utilize those glitches. The stages being yanked are getting the bum's rush because they're not very popular.

Seems that Nintendo is pulling stages that haven't gotten much play from users online. In some instances, stages are banned and unable to be re-uploaded by the creator, even with significant tweaks. These deletions/bannings come out of nowhere. The only 'warning' you get is a blurb from Nintendo's guidelines, which state that a level can be yanked at any time due to lack of popularity. While Nintendo doing this doesn't mean you're in any trouble for your creations, it does kind of suck that levels people poured hours to aren't allowed to be viewed worldwide anymore.
