As you are probably already aware, volumptuous accidentally invoked dupeof on a video that was not a dupe.

As we've mentioned on a few occasions, the dupeof invocation is extremely sensitive, and you must use extreme caution when invoking it. You MUST WATCH BOTH VIDEOS IN THEIR ENTIRETY before you invoke dupeof!

For his misuse of the invocation (which has caused a lot of difficulties for us to only half-way "fix" [because a full undo of a dupeof is impossible]), the dupeof invocation has been revoked for volumptuous indefinitely.

This is a new one-strike policy for any misuse of dupeof due to the severity of the results of such misuse and the offender's apparent unwillingness or inability to use it appropriately/responsibly.
