Due to getting a lot of unorganized requests for this, consider this a hide request page! Yes, editors and moderators can hide posts, but I've had several instances where the things that need to be hidden are simply outdated, rather than breaking the rules, but the people involved do not have hiding abilities. This tends to happen most with tournament pages and so on.
This page is only for your own posts that have other answers on them or tournament meta posts that need to be hidden. If you find a post that's breaking the rules, simply flag it and it will be hidden.
