Anti-Union

An Anti-Union is a Union that aims to destroy other Unions and organizations. For example, an Anti-Union might crash another Union's events and flame/spam their thread until that Union gives up. An Anti-Union might also declare war on any Union/clan/organization that is not allied to them.

At least one Anti-Union has caused enough trouble for Jagex to take notice. Several years ago there was a sticky in the Clans Discussion Forum on the RSB titled "No Anti-Unions".
