Is it okay to answer a question in a spoiler block? I am curious since almost no answers use it.
I've used spoiler blocks fairly often, always after providing some hints.
A bit more often, I'll provide hints and say something like: "Can you take it home from here?"
I don't recall getting any direct pushback, or even any downvotes, from other users when I've done so.
I have no idea how many OPs have taken me up on my hints before heading to the spoiler, but people visiting the question in the future may do so, even if the OP doesn't.
