The same goes for comments on talk pages, edit summaries, and, yes, even usernames.
Which are still covered by our etiquette and usernames polices. If somebody makes a pest of themselves and wastes our time and energy that would otherwise go into creating an encyclopedia, then they must change or leave for the good of the project.

User names should only play a nominative role, not a provocative one where slogans, insults and POV statements reign free.
