The spoiler tags used in Eternity >!!< don’t seem to be compliant with how the majority of Lemmy apps handle spoilers. The web UI for example uses the following:

::: spoiler spoiler

:::

It seems most apps follow this (Voyager for example).

This causes spoiler tags made with Eternity to be ineffective, since they don’t show up as spoilers and vice versa. This can become quite annoying in communities discussing movies, tv, anime, books, manga etc
