About a year ago I asked a question on a somewhat new StackExchange site. The question was up-voted a couple times, I got my answer and I accepted it.
Then, a couple months ago, someone found my old question, marked it for deletion and then down voted it. Someone must have noticed the down vote and deletion flag from the active questions page, and they followed along and did the same thing again to my question which had been completed and inactive for about a year.
The problem is, their behavior was correct as of the date they flagged my question. The point of the site had been solidified and my question was, technically, inappropriate.
However, a year ago that wasn't the case. The full intent of the site was still being discussed in meta, and the FAQ description hadn't been fully nailed down, so my question was acceptable.
I have a fair amount of reputation on this site, so I wasn't not grossly offended by their actions. I am curious, though; was the behavior of the down-voters inappropriate since my question was historically acceptable and had an accepted answer?
Please note, this happened a few months ago. I'm not looking to complain within the comments of my question. However, my question regarding the etiquette of this scenario has bugged me-- I'm genuinely not sure if this is considered appropriate behavior or not because I can see validity with the idea of either cleaning up old, no longer unsupported questions OR leaving them for historical reasons.
