The perk is the wrench UX denoting you are an employee to the community . Reddit/twitch allow employees to communicate with the users . It is a social media platform , being able to indicate that you are special is street cred.

The other access rights that come from staff access is either incedential or miss /debt in architecture.

It's understandable why this is a neat perk, but it also seems absurd when you look at Twitch as an entity owned by a global corporation.

Man oh man, big "No thanks" to a perk like that from me

"Hey, pick through everything I say with a fine-toothed comb and treat it as the official company stance!"

From prior (user) experience, typically staff have non-wrenched alt accounts for just chilling out in streams (with less concern about conduct, but generally tame by twitch standards). But will wrench up for higher profile streams or folks they're otherwise pretty close with personally.

I suspect that's a lot more controlled these days, but it wasn't very uncommon for signified staff to be trolling along with everyone else.
