Message about disruptive user I am not an administrator so I can not block the disruptive user You could report this person to Wikipedia Administrator intervention against vandalism and or Wikipedia Administrators noticeboard Incidents I must say that there are several possible reporting noticeboards which makes it a little difficult to decide which one to use for a problem that involves more than one issue but I think the above two are the most likely for this one You can see other suggestions on the general or main Wikipedia Administrators noticeboard page
