Thread:Project:Support desk/Page Tags/Categories/reply (3)

The problem with the categories is that they are done like a simple internal link in the main editing field, not in a separate field where there may be extra conditions. And as you can put a link to let's say jtvznruitqae :-), you can also choose a category YOU want to put a page to, like Category:jitzntrap. So in WP or Commons there always is the danger that there are categories which are double or triple or which are useless or senseless or something else, and there are also people whose work is just cleaning all those category "errors". As I say, as it's simple text in the content field you can't prevent what people are doing there, just cleaning it afterwards or banning people who don't look at or ignore any conventions. Maybe there is an extension which add separate category fields, but probably it does not prevent adding categories to the text.
