The 200 repcap is obviously a dupe of many questions. So I'll skip that.
As for why that user got a huge burst of votes in a such a short amount of time:
The question was linked from Hacker News: http://news.ycombinator.com/item?id=4238696
That brought in a large number of votes (and views) in a very short amount of time. This is quite common and can happen to any question new or old.
However, the question itself is apparently "not constructive". So it accumulated a bunch of poor answers over the past few years. When it was finally linked on Hacker News, it brought enough attention to the question to get it closed and get all the bad answers deleted by moderators.
Because of the large number of moderator deleted answers, the question was automatically protected by the community user.
