Logic bombs are unprofessional
Implementing logic bombs is unprofessional and can get you into problems.
However oversights in documenting procedures are for your ISO-9000 or ISO-14000 compliance people to handle.
Also, if temporary measures not documented in the operational manual are taken, make sure they don't become a regular part of your operation, always put a time limit on them so they disable themselves when not needed any more or after they *should* have been reviewed. Extend those times at your discretion.
So please, don't be unprofessional and create code to wilfully damage your employers systems. Just follow procedures as documented. That's creates just as much chaos and is a lot harder to repair.
The nuclear explosion for obvious reasons as nothing is a destructive as strictly following procedures.
