The one time as staff I ever fudged things in my favor was on the first site I personally admined, back when I was a smol bean (probably about thirteen). My elder sister RPed on the same forum, and both of us shipped one of our characters with another character on the site, resulting in this completely unplanned love triangle plot that I genuinely to this day don't know if the third RPer was actually into at all, or just went along with because he was nice, sdfjlkhdkjfdhs. February rolls around, and we ran a romance roulette event - y'know, as you do - and the dice roller put together sis's character and this dude. My brain was like, "Oh no, if that happens, they're guaranteed to get together!!!!" Not only did I fudge the results, but I did it after I told my sister about the initial results, so it was???? *wipes sweat from brow* I didn't even swap with my character, and I'm pretty sure the whole event fell through before it even launched, but I felt so guilty about that one (1) situation that it... it haunts me... to this very day.............

Outside of that, the only time I ever really fudge usually randomized rolls is for narrative purposes/interest, and never for anyone's particular harm or benefit. It's always struck me as weird to hear about people's experiences with staff that supposedly abused their positions to give themselves an obvious advantage, because the one time I ever tried that, it felt so icky, and doing that completely defeats the purpose of even trying to keep up a front of mechanics or randomization? I don't mind people doing what they want on their own forums, since you should enjoy yourself on your site, but at that point, just don't set up a pretense of something you're not. Especially when it gives other admins a bad rep for when the dice fall in their favor. *sweats profusely*

also bouncing off what pharaoh leap said-

the only times i have ever nudged rng to change results as a staffer (at least that i can remember) are when i was doing thread roulettes, and it was never to anyone's actual detriment - it was always "oh no this member hates that member let me nudge that a little bit" or "omg no this super fast newbie got paired with this super slow established member we're gonna be fixing that" or even once "mmmmmmm i think this person might have ditched so let's just quietly nudge them to end up with me so it's my problem." like don't get me wrong, sometimes i was really tempted towards crappy mod rolls for some members who drove me absolutely nuts but i don't think i ever gave into my wish to destroy them with wild pokemon (if only because i didn't know if they would genuinely want the crappy pokemon i'd give them tbeh-)

nothing sucks more than when you get a few members who just don't like whatever new additions or updates you've rolled out on your site. as if trying to provide more content for your member base means that certain plans they might have are derailed and it is absolutely your fault for not being a mindreader about things.

sometimes i wish it was a lot more acceptable to just. "hey this is the core idea for a site, take it and expand on it as you see fit" (or really any kind of setup where you can hand off some of the development stuff but not be responsible for the staffing portion) since like..... there's so many rp ideas / sites i would love to be on but just don't have the time / energy to actually staff
