1. A lazy class of Wikipedia Editors that take no time to research content, but rather vandalize a Wiki article with numerous "Citations Needed" Tags. 2. People that do not contribute in any meaningful way to Wiki profiles. 3. So-Called Editors that place "Citations Needed" tags on common info that can not be sourced. 4. Vandals.
Wiki Citers are such a waste of life. It would take 5 minutes to find valid sources to backup profile content. Instead they just blanket the profiles with Citations Needed tags, instead of helping Wiki's look professional.
