I was trying to Like a comment in this thread using my smartphone and accidently pressed Unlike instead. Tried again twice more and the comment disappeared. My apologies, but can the comment be recovered? Also, can the Like and Unlike buttons be separated more? Sorry, and thanks.
Pressing the thumbs up or thumbs down will replace any previous votes the other way on the post. In other words, only your only most recent vote will count and previous votes will be disregarded. You must have hit the little flag button, which throws the post into moderation for administrator review. When nothing is found of any consequence on the post, administrators reinstate the post, so no harm is done.
