We're introducing a new rule that applies to all servers: @Server Admin please read: http://plaguefest.com/threads/what-you-need-to-know-about-the-new-no-third-party-tools-rule.22085/ The main reason this wasn't a rule before was we knew false positives were possible and could affect innocent players. However, after conducting a few tests and tweaking some plugin and server settings, we're confident we can now accurately detect and enforce this.
Thanks Brian. Would like to see the rules and procedures regarding the new rule, would you be willing to make it public?
You can find the rule on any of the server rule pages, but punishment procedures are for admins' eyes only.
