I've noticed some people added categories that are just plain numbers like 1,2,3,4,5,6,7,8,9,10 well I think you know story. But anyways we should remove those and when you try to add them they won't count as a category and won't appear in the page wiki activity or yeah you know just to trick the spammers. We should not remove categories like countries that use to be 3ball 2ball or 8ball because they have numbers in them. We should also add a categories that have flags that look alike so none can get confused like country flags that look like USAball but would not be use to spam if they look exactly alike or they have one little same detail.
