Which boils down to "I am planning to have this setup, is it secure?"
And about an hour later, I realized I had made a mistake in my reasoning. The setup as described was not secure, it was easily breakable. So I wrote an answer on my own question. https://security.stackexchange.com/a/85988
And now I'm getting downvoted and comments on how my answer doesn't answer the question. ... What the... ? How does the answer "It is easily breakable via method X" not answer the question "Is this setup secure"?
Maybe I'm wrong to answer my own question like this and I should update my question with my idea instead. Except that invalidates an existing other answer. Also, it's basically moving the goalposts by going "come and help me fix my system."
The other action I can see is just deleting the question. I already have my answer, thank you, so the question is no longer needed. That's... not what StackExchange was made for. It's a Q&A meant to become a reference guide. "I have my answer, so lets remove the question" doesn't match very well with "let's make a reference guide".
So what would you have me do?
I don't have the expertise to enhance my answer further.
I'm apparently in the wrong by answering my own question.
I don't see how editing my question would improve the situation.
I don't think that deleting my question is the correct course of action.
Also, canned snark like "This does not provide an answer to the question. To critique or request clarification from an author, leave a comment below their post." does not help when you're both answer author and question author - what, you want me to ask myself?
I say my answer is okay.
