Back in the day, we-the-writers (I say 'we' even though it was before I joined the project) developed the collective notion that it would be funny if SCP files included Hilarious Threats(tm) for silly personal misuse of SCP items — "Keter duty", "demoted to D-class", etc.
More recently, and as the demographics of the project have changed, this has become strongly deprecated, to the point where some individuals cite Hilarious Threats as a rationale for downvoting.
Aside from their inherent silliness, the most common (Keter duty and Demotion to D Class) don't even make sense from an in-story point of view: you do not want individuals on Keter duty who are (irresponsible / incompetent / angry at the Foundation / etc).
Similarly, if you know what "D-class" really means, and you've been demoted to D-class (thereby giving you a damn good reason to hate and resent and oppose the Foundation), what's gonna stop you from using your inside knowledge to (for instance) spread dissent, etc?
"D-26377826, do this unpredictably dangerous thing that stands a high chance of killing you in a horrible way." "Fuck you, mister scientist! You're gonna kill me at the end of the month no matter what! I ain't helping you with nothing!"
Salary cuts, yes. Official reprimands, yes (as in the guy who asked SCP-294 for 'a cup of what the next guy orders'). Demotions in rank and/or loss of privileges, sure. Being transferred to other projects, or even to paperwork (as in the guy who suggested we give 682 a bunch of flowers), yes. Unsanctioned retaliatory killing of other Foundation personnel which is then covered up, sure. "Anyone subject to circumstance X will be considered unrecoverable", sure. "Anyone who attempts to bring an open flame into SCP-811's enclosure will be terminated on sight", sure.
But "if you use SCP-159 to get privacy in the shower, we will kill you" - that's just stupid.
I hereby suggest that an explanation of why Hilarious Threats are unacceptable be added to the How To Write An SCP page.
