I think it is necessary to remove the bot accounts(especially of vjudge) from the standings of most submission. It is really annoying to see that most of the top positions are occupied by bots and the human users are being underrated.

Folks, I hope you will think about this.

I have noticed that the questions in the gym section only provide the sample test cases even when I submit a solution. It makes the debugging process really tough. It will be great if at least one test case is provided where my code has failed.
