Last day another cheating case got my attention.
In codeforces, we are here mostly to learn and practice problem-solving. What is the benefit of such a rating increase, if you did not earn it yourself? Where is the honor in that!!! It's not like in an interview, you will be passed, just because you have a good rating. You will be asked questions, what will you do then!!!
Codeforces might introduce a Hall of Shame list. If someone is caught in such cheating cases, their profiles may be archived, so that the cheaters can not delete their profile and displayed in the "Hall of Shame" profile. Codeforces can level these profiles as bad practitioners/cheaters.
However, some hard steps are needed to be taken, maybe then these kinds of cheating will be reduced.
