recently it came to my attention some people using custom INPUTS(RIGGED) in their code and manages to hack the solution with another id Lets assume a code that involves a string input based output. for instance if I use a specific string in my code(ex: my name or a random string that only I am familiar with. and say if I give that string as input it will generate a different output than what the problem really asks for. then manages to hack the solution with another account. can Codeforce take any steps to prevent this from happening, it really disturbs the actual objective of hacking someone's solution.
