Improving the Backend

Maybe We could improve the Backend with A better Reputation Checking Algorithm just like stackoverflow's or some calculation Stuff 🤪

The issue does not name any files, tests, entry points, or specific reputation rules. First inspect the repository to locate the backend code and determine whether reputation checking already exists. Before implementation, clarify the algorithm, inputs, expected calculations, and acceptance criteria; done should be defined by maintainers and covered by tests.
