This question already has an answer here:
Once I asked a question but unfortunately it got closed. So I edited my post and voted for it it to be reopened. 2 days later I got 4 votes, but never got the last one. Yesterday I spotted that the count of votes oddly dropped to 2, and today only 1 remains.
What's the matter? Can voters retract their votes? I tested this, but it seems there is no way to retract my reopen-vote.
So I suspect that reopen-votes have an expiry time. Is it true?
