⚠️ Re: Content Warnings
That's an interesting example. A considerate approach that can be "solved" in more ways. If you set your post to Welsh other people can choose to filter those out if they want. But that's a more complex setting, so I totally get the CW in this case.
I noticed Mastodon set the language of this reply to Welsh(!) so I need to change that before posting. I do wonder how that is supposed. Perhaps that's your default setting?
