I've noticed that closed captioning automatically filters swearing. To be honest, this is less than ideal. It assumes your hard of hearing and hearing impaired users need to have language filtered for them, to a standard which non-hearing impaired users don't. An important part is all language translated accurately as possible, otherwise you are directly deciding what language is more important for the disabled client. If a person wants to engage with streamers that swear it should be their choice whether or not they want to see that content, not chosen for them.

Please note: How to handle slurs within closed captioning is a topic of debate, and I do not mean those, I mean words like **** and ****. If these words are okay for twitch, they should be okay for disabled people to have transcribed.
