If someone contributed to starring a sandboxed question, and just after the question got ~3 votes, they posted their answer and then un-starred the question. As intended, no further answers are allowed, which would temporarily make the starrers focus only on their answers and make them get more stars than usual. Is that an intended behavior or not? If not, how can it be avoided?
You are absolutely right, this kind of abuse is possible, however…
3. The best questions will probably launch quickly and decisively  if we get to the stage of having a lot of activity here. Removing a single person's vote isn't likely to make much difference at that point.
