Well, if you see a world unreported please report it. Unless, you don't wanna look at it. In that case give it to me or anyone of the other mods and they will take a look at it for you.
If they don't get reported, there is no way there gonna get deleted completely from the community content. Kaalus has added that auto delete so he won't have to deal with the content. So, he can work on the features faster. It probably might be a good thing to have mods on the content page but, that is up to Kaalus to figure out.
