What happened to [spoiler] tags?

[NiceCupOfTea]

Just tried to use them and they don't appear to be there any more... They were useful!

They were turned off a few years ago, but I'm not sure why. We'll take a look and see if there is anything stopping us from turning them back on.

Was going to use them so that people could avoid seeing a pic of my broken toe if they wished!
