The other day I was talking with some friends about the “old days” before Mastodon supported CWs, and how we used to EBG13 nyy bs bhe cbfgf because, guess what, if Mastodon didn’t have CWs we still wouldn’t throw nyy guvf fuvg out in the open. I realized that I actually kind of liked ROT13 better than the current system, because you could only ROT13 ⁜cneg⁜ bs n cbfg and the remainder would give the reader context as to how the problematic bit was being used.

Then I realized that our old ROT13 system was an effective plaintext fallback for pbagrzcbenel Qvfpbeq-fglyr fcbvyre gntf and that I could just implement that in Mastodon, so I did.

GlitchCat users! You can now create inline spoilers in your posts by using a <spoiler-text> HTML tag in either the Markdown or HTML content modes. Spoilers ⁜can⁜ include emoji but ⁜cannot⁜ include other markup like links, mentions, or hashtags.

Spoilers federate as ROT13 with special properties so that other servers can recognize them. If you are on another Mastodon instance which supports Markdown and HTML content modes, let me know and I can get you a patch!

(here is what this post looks like in the frontend for those of you on different servers btw)

@Lady hmm, might be a good idea to make it work on the public view too?

@alyssa i’m ambivalent since the current public view will disappear in 4.0 (it’s all going to use the frontend JS; see mastodon.social which is running this code now)
