Out Of Wynncraft Trading

I have been playing wynncraft for a few years now and have moved on to other games such as csgo, DOOM, and TF2. All my in game items and hard work are now useless due to the fact I never log on to minecraft anymore. I have considered trading all my LE for items such as a csgo Karambit, but that is against the rules and would get me banned (Although I don't play wynncraft anymore, I have spent a bunch of money on this server and would not like to see it go to waste). Is there any way I can use my in game money for other things without getting banned?
