The sequence of actions I do to spoiler an image are:
1) open the thread
2) click on "Moderate Thread", to enable the moderation actions
3) select the checkbox of the post to spoiler, in this case the OP post
4) click on the "Spoil files" button, from the actions panel at the page bottom (this action doesn't seem to require the captcha)
Then I get the "Files spoilered" confirmation message, then nothing happens
This same operation did work previously, these OP images were spoilered manually >>>/dump/432 >>>/dump/818 now it no longer works

Out of curiosity, there exist other places from where it's possible to spoiler, aside the "Moderate Thread" viewmode?
