This question was recently locked (I only know because I had a bounty on the question). As Sky's comment points out, this problem is part of a current USAMTS competition (deadline to submit solutions is November 30, I believe). Right now there are two quality answers even though they have been "temporarily deleted."
My question concerns the effectiveness of locking contest questions, particularly when quality answers exist. These answers are still visible to >10k users. Isn't this a problem?
Presumably, >10k users aren't abusing contest rules, but this is only a presumption. It seems odd that answers should still be visible when a question has been locked because it is part of a current contest. Even if the answers were trimmed, the edit history would still be visible. Is there a better way to lock contest questions that have quality answers? Having the answers still visible seems to run against the spirit of why the question was locked in the first place, namely to prevent any unfair advantage in the contest. Is there any way to more effectively lock these types of questions (e.g., only moderators can see deleted answers to contest-locked questions as is the case with deleted comments) or is the system fairly well fixed?
