"Everything you want to accomplish becomes an IC effort they are not inclined to help push along."
The only person pushing your IC efforts along is you, the player - GMs don't push any player's IC progress along. We play things as they lie and step in when support is needed to make the current or the next step of a goal which has been ICly achieved happen, or to provide an avenue for progress when it's impossible for PCs to do so and it's themely and right for the game.
(I am not speaking to Kuroyama directly, though their comment inspired this response. I'm going to use the pronoun "You", but I'm speaking to everyone following along or finding this in the future and finding out from the BGBB how Sindome works, as I did when I was a new player.)
Here's the thing.
GMs may elect to make the IC world do things which support your IC efforts if you're playing smart and ICly earning next-steps along your path which can't be achieved with your own roleplay with PCs alone. Understand this: A hell, hell hell of a lot of everything in the game is earned off other players, not off GMs handing out prizes. We're here to support your roleplaying so that it results in MORE and cooler roleplaying, for yourself and others. We're not here to give away cupcakes and sprinkle win-points on them when you ask for it enough and jump through the hoops you think we want you to.
GMs won't elect to do anything for you if the things you @note and xhelp about are only asking for things which you didn't ICly spend effort chasing and/or which wouldn't yield ANY benefit to your roleplay with others or any benefits to the opportunities for others to roleplay based on what the handout would do to your character's progress, achievements, acquisitions or position.
(I know what some of you are thinking. "xhelp Hi, have <someNPC> <give/make/show> me a <clue/position/loot> please because I GUARANTEE you I will use it to make <jobs/conflicts/capers> for <group/faction/individuals> and enhance the game for everyone as soon as I get that!" No. Show it, don't tell it. Prove you can enhance the game with your roleplay first, then ask for the thing you NEED to keep going in that direction.)
This is the reason GMs won't help anyone end their character. If you're not shrewd enough to roleplay your character's exit from the game in a way you're personally satisfied with as a matter of theme or trueness to that old character's constitution, makeup and story, AND in a way which is OOCly thoughtful to what the result of this absence will do to other players ICly and OOCly, then you're probably not shrewd enough to roleplay your new character in a way which we would spend effort to hurry along into the game world.
We're not here to help you STOP roleplaying, and, if you're that half-assed, thoughtless and negligent with the way you end your unwanted character, then the idea of helping you to hurry to START roleplaying someone else looks just stupid, doesn't it.
Again. My use of the pronoun "you" here is not aimed at any specific player. I'm explaining the GM thought process in general because a whole bunch of different uncertainties, questions and misperceptions have been raised above and over xhelp.
It's true, though. If you cause someone else's roleplaying to be FUCKED UP because of your OOC neediness/attitude/laziness, it's about the worst thing you can do to a player and to the game.
It's abominable how much IC activity there has been over a series of unrelated but unfortunately similar OOC acts. If you want to stop playing, or stop playing a given character, it should happen in a way which Withmore barely even notices, if at all.
