Well...this conversation certainly took a turn...
I don't think the /check is the important part of this conversation. The same social contract applies to an infinite number of other requests.
If your LS mate asks you to call them by one character's name over the other character's name.
If they ask you to call them by their first name (or not)
If they ask you to trade them stuff instead of bazaaring it
If they ask you to send them messages on Discord instead of in-game
If they want you to set a lockstyle
If they don't want you to jobemote them
If they don't want you to follow them
Or whatever other unimportant, insignificant request they make of you. If they make this request repeatedly and you don't follow it, you're the *** in the situation.
If you then go online and hide important facts about that situation, you're doubly an ***.
If I posted a thread saying "AITA for calling my friend Rob, his given name?" then it turned out that Rob was worried about being dox'd because he's the only Rob in his small town of 35 people in the Midwest, and he repeatedly told me for months not to call him Rob, and ESPECIALLY not to do it infront of Sinistral, who lived in the same small town as him, and I intentionally waited for Sinistral to join the Discord and then LOUDLY proclaimed "Hey Sinistral, do you know ROB?!"
Then um...that would be a *** thing of me to do. Even if I/you don't think it's a very serious problem. That's not up to us to decide, it's up to the other person to decide.
And it's not about video game pixels, it's about human beings.
Edit: for another example, since I offended your delicate feelings with the last one. Say, hypothetically, there was an online database where your company/government made people's salaries public by request. If this system sent an email to the person any time their salary information was requested and they were uncomfortable with you looking their salary up...you could say "turn off the setting where you get notified if it bothers you" but...if they specifically told you they'd rather you not look up their salary, multiple times, and you still looked it up...you're an ***. I'm sorry, I don't know how else to explain it to you. It's not the notification that's the issue, it's the thing you're doing in the first place.
