Do you upvote your own posts and comments?

Since on most fediverse instances you don't automatically upvote your own comment, do you do it manually? What's considered "proper etiquette"? Because on Reddit your stuff is self-upvoted automatically, while in YT comment sections comments with 1 like sometimes get called out for liking their own comment. Do we have an established standard here yet, and if not what are your thoughts on it?
