I upvoted a question that looked promising but the questioner just abandoned the question not giving any more info and nobody could answer it because they abandoned it. I'd like to remove the 1 vote and if anything, downvote it. But I can't even remove the upvote.

It says I voted on it on jun 16th and the vote is locked. I think I probably tried weeks ago too but no luck.  Where is the sense in that?
