On a related question: I just posted a question to the forum, and once the page refreshed on the question I had just asked, it already had one vote. Is this an auto-setting where my questions get automatically upvoted by me, or did someone really upvote it in the few (mili)seconds before submitting it and the page reloading?
All of your posts start with a strong upvote from “you” automatically. Your comments start with a normal-strength upvote from “you” (as they do on Reddit). You can undo these votes the same way you’d undo any of your other votes.
