- When somebody searches for a handle that doesn't exists, we get Cross-Origin Request blocked and the status code becomes 0 in jQuery. So we can't determine if the user doesn't really exists or some other network problem occurs.

 - When counting number of solved problems, some problems that appear both on div 1 and div 2 get counted twice.
