It's not part of the "punishment" here.

Cyrax, no one disabled your reputation for discussion of other drugs. We don't have that capability. You did have several infractions, however, and what may happen when you have an infraction tally that results in a ban is that the system automatically shuts off your "reputationometer" while you're gone (just like avatars and signatures don't show during that time).

You should be able to go into your User CP/Edit Options at any time and recheck the box that allows your rep to show. Give it a try.
