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.
