Hii, sorry for getting late to you. I believe that is refering to the SKippable Start Cameras hack/setting in the launcher.
You can enable it by going to the Settings tab in your Launcher then scrolling down until you find the setting.

Correction: that hack is banned. The rules are referring to an ingame glitch which is tutorialed here:

This glitch can be carried through to the main menu, therefore you can activate it, exit to the main menu, load the game, and then continue.

Yeah as it turns out the sounds do play but there are some nuances. This was learned a while ago.

• You need to have the camera facing backwards, with Homer looking towards the camera, and then enter the trigger(s). This is either a very weird bug or hardcoded.
• The sound effects have a probability to play rate set in a SPT file that determines the chance of each one playing. The rate is always set to less than 1.000000 so they won't always play.

Deadnaming is when you refer to a trans person by the name they went by before transitioning.

It can be incredibly painful for a trans person to remember the part of their life when they couldn't outwardly express themselves as they felt on the inside, it can feel as if any progress you've made since that previous part of your life has been suddenly invalidated simply by hearing or reading the name. It can hurt to even know that people know your deadname, even if you know they'd never use it. Knowing people even have that mental connection when it comes to your deadname can be a horrible feeling.

It may not directly put the community at risk, but it's incredibly hurtful to many members of the community who either know firsthand how it feels to experience that, or to members who have trans friends or family members who've seen the toll it can take. Thank you for asking, and if you have any more questions please feel free to ask.

This looks really informative and should help lots of people. Good job!
