I recently asked my first question here. In my first version, I used a spoiler block to hide most of the text. Soon after, a mod passed by and edited the spoiler block away, leaving all the text visible.
Later, I got downvoted for "spoilers", but it is not given if spoilers in the title or in the body. After I posted my comment, explaining to the user why I thought I did not spoil anything in the title, and that the body got edited, I have received no further explanation.
Can someone help me understand what is the policy here about spoiler blocks? When/how should they be used?
Note: I don't want anyone to pile on the downvoter or the mod, I understand why the downvoter behaved that way (even if it appears to be against community consensus), and I understand that the mod wanted to help me with my first question. I am here to ask you about site policies, not to crusade against this or that user.
