Good Evening

Actually system administrator can do alot of thing:
- delete post
- adjust reputation point, for example change 43 points to -99 points
- disable reputation power
- undo zap
- tag off topic thread
- close thread
- reverse zap
and many more...

So there is no need for Boss' clone to hide in newbie session. Boss' clone can openly post his message to get zap. After the game, he can remove the clone from database.

Believe me, VeryClever and HumbleFeedback are not clone of boss.
