Straight out of the rules.

Listen to staff members - Enough said! People will always find ways around the rules, staff reserve the right to make changes to the rules to cover these holes in order to keep the server a safe friendly place.

Any form of cheating will not be tolerated - This means anything that gives you an unfair advantage over players who are playing the game the way the game was intended to be played.

You have been told by several staff including 2 of the longest serving admins on Craftymynes not to use them. So there isn't a sign it's common sense which sadly is a rare commodity these days. If we wished you to have jump boost or speed it would be given to you upon entry into the parkour.

If you are unsure about something ask first, this whole situation could have been avoided with a simple question.
