@runescryer I think whether or not it can work depends largely on what kind of support you have in place for that person.
Clear, written policies with a clear rubric for when certain things will be awarded, clear guidance and help on how to get and launch RP...the more crystal-clear the policies, the better this would go. And anything that looks vague should be tightened up.
@derp and I were talking about this last night. Say you have Tier slots for different characters.
Vague: Top Tier characters must foster RP in their spheres.
Specific, crystal clear: Top Tier characters must run 3 PRP scenes per month for that they do not participate in personally. This may be for any sphere as long as you're making RP for the game. Those PRPs must create RP for at least 3-5 people per session and at least two of them must have entirely different participants. RL happens, so you get a 30 day grace period. If you can't uphold your obligations you will be asked to step down from the Top Tier role and will lose all the benefits, even if this means putting this character on hiatus and being invited to app a Bottom Tier character. Top Tier characters may be reactivated after running 5 PRPs.
Then when the ombudsman/player relations guy gets:
"@Derp was totally mean to me! He dropped me from my tier role unfairly!"
Well now there's something to investigate and something to work with.
"Hey Derp, unhappy player ran his 3 PRP scenes last week, did you spot that? They appear to be within the bounds of the policy you wrote, man, is there something else going on?"
Or...
"Hey, I see that you tried to run your 3 PRPs but that third one had three of the same players from the first two so you're not in policy yet. Do you think you can run one that meets the criteria in the next week? This has never happened before, seems like a mistake. If so I'll ask Derp if you can have some more time."
Or...
"Dude you're way past your grace period. The policy clearly states you lose the character in this circumstance. I'm not going to Derp with this. Go run your 5 PRPs, and put in your requests to get your character back, same as anyone else."
If the policy isn't clear the Ombudsman themself has no leg to stand on other than gut, what seems fair, their own feelings towards player/other staff, etc., and you end right back up at square one.
