Open an RfC on this user. List some examples of "POV pushing". If
Scandum is not citing sources for his additions and/or is ignoring
sources supplied by other users, then he IS breaking rules. Keep in mind
that an RfC on an individual should focus on personal behaviour and not
content issues.
Some users respond positively to being the subject of an RfC; others
don't. If Scandum doesn't, you may have a good case to bring before the
ArbCom.
