I just sent Moviesign a quick message on this topic, but I figured I'd post about this. I've noticed people blanking pages that they dislike, namely @Bbbbbbbbbbbbbbbb9bbbbbbbbbbbbbbbbbb and @CoolEgorchik2012 .
If you dislike a page and want it gone, please add the {{Delete}} template and discuss it with others. Blanking pages counts as vandalism, so do not do it. If a page needs to be deleted urgently, contact a content moderator.
However, CoolEgorchik did bring up something that I think we should talk about. The "Flex your ______" and "Get to Know ______" pages are mostly in violation of Rule #3, except for "Flex your edit amount" (Which can be easily explained) and on occasion the "Get to Know ____" pages (If they are on an OC and not an actual person).
Otherwise these pages should be discussion posts in the "Off-Topic" category. They do encourage people to contribute to the wiki, on the other hand, and I am wondering if potentially these pages would be worth a breaking of Rule #3 to keep up. We can discuss this issue in the comments.
