Consider supporting my work and buy the premium version, it has quite a few extra features.

Changelog:

• Player is now untagged before triggering kill abuse commands
  
• Fix issue related with PvP nametags
  
• Messages in messages.properties are not sent if they are empty
• Really force fly off in case the player can use /fly while tagged
• Money reward now gives a percentage of the dead player money

If i go a long time without uploading here, check the dev builds or github for updates.
