"Citation needed" is a silly phase mostly used by power-tripping censors at some American propaganda site called Wikpedia. It is used to tag things the censors would like to censor. Adding a ton of citations will typically results on those citations being removed with a silly "Not credible sources" tag.
Citations are usually not needed, like ever. Sometimes discussions are, so something like "Discussion on the talk page is desired" tag would perhaps be useful. "Citation needed" tags are not useful or needed or required or desired and they should be eradicated as soon as possible if they are found on this website.
