After talking with a moderator on Gaming.SE, StrixVaria, regarding a question issue I have, I'm largely curious if there is an unspoken or somewhat hidden rule of not self-answering if you are high rep and leaving the question to answers from other players?
Question in context: How do I change my Profile Icon?

Context: I posted a question which I immediately self-answered. Some users found it fine to downvote but largely the issue was perhaps that I did not let other users answer the question first, especially as a high rep user.
I know about the so-called "Fastest gun in the west problem" but that doesn't pertain to self-answers.
Is there a "Fastest Gun in the West" issue with self-answers? Is there an issue with a high-rep user self answering first? Is there an unspoken rule in the whole of SE regarding high-rep users in conjunction with self answers?
