Is it possible to make spoilers inside blockquotes?
> text > more text > >! spoilery text > text > more text
How about multiline spoilers?
>! Spoiler >! Mor Spoilerz >! Still spoilery
Finally, quotes inside spoilers?
>! Spoiler >! > The spoiler said stuff >! > The spoiler had more to say >! More spoiler
It specifies none of these on the Formatting page, but the syntax is so similar between blockquotes and spoilers, so I don't know if it's possible
