A couple days ago, I ran across this question. As you can see, it makes unusual use of spoilers and has a section marked off for "extra tags" because apparently the author didn't feel they were allowed to add enough. I edited it to remove the extraneous tags and changed the spoilers to just regular quotes (not that that's much better as formatting goes, I guess). It appears the author has rolled back my changes and added back their odd formatting and extra tags. I don't want to get into an edit war, so I'm just curious, is this considered OK? It seems really weird that part of the question is hidden for no good reason, and that the author had to add extra instructions on how to read it. It seems like it makes the site less useable.
Looking at the related Meta question Should Use Of Quote Blocks Be Restricted To Quotations, it seems like it was valid to edit the question, but that I should have used headers instead of block quotes. Should I just flag the question? Or should I just let it go?
