When I was submitting my code just now, I noticed that every submission spends several minutes in the queue. Then I opened the status page and realized that many of the recently submitted codes come from accounts that are not rated.

It really looks like these accounts are bots. A huge number of them started being active today. None of them have names or countries set, and their handles are random and very similar to each other.

Please do something about this bot problem. It slows down the judging queue and affects everyone.
