I’m curious about your use case for not wanting cycles? Is it potentially messing up your accounting somewhere? If you don’t want them you can send them to me. 
At one point we had someone build a ‘cycle dao’ where you could mint out tokens to users that sent you cycles to support your services. It might have some interesting code for you: Completed: ICDevs.org - Bounty #17 - A DAO for Cycles - $10,000 - ht: cycle_dao
