This question already has an answer here:
A question was posted a couple of days ago that was blatantly off topic. I do not yet have 3,000 reputation here so I am unable to vote to close a question. Instead I flagged it with the "Blatantly off-topic" reason:
One minute after I flagged it, someone edited the post to make it ask for a site recommendation for where to ask the question that had originally been posted. Now, of course, the question is on topic. The question went through the close review queue and unsurprisingly got three votes to be left open. This caused my flag to be declined.
As I understand it, there is some kind of penalty for having a certain number of flags declined. It seems odd that I could possibly get into this situation by flagging a question for a perfectly valid reason which only became invalid due to a change that was made after I flagged it.
Is this status-by-design? Should I not flag posts for closure due to the concern that they might later be edited which will render my flag retroactively invalid?
