I know these are in use on many forums (especially forums regarding films, TV shows, etc.), what they do is simply hide the text within them and replace it with a "show spoiler" button, which when clicked, shows the text.
On a forum like this, there could be two uses for this feature: firstly to hide plot spoilers (their normal use), but also to hide translations. For example, if someone wants help with their Russian, people could provide a reply in Russian followed by a reply in English in spoiler tags.
Example:
