Rehabilitation of cheaters.

:smile20:
then, using his nickname "Dirty_Player," Kostya tries in every way to hint that heroes haven't seen such a malicious cheater as him yet. He should be awarded the "Champion of Cheating" award immediately!

The nickname itself doesn't mean anything, of course. But combined with his actions, it already says a lot.
For example, Dirty's actions tell us that his nickname is just a joke.
In Exit's case, it's the opposite.
When people were guessing what kind of Heroes 3 clone it was, Exit quietly sat on the sidelines and blended in with the background. But when Dirty presented the screenshots, he readily shared his grief with the community. What prevented him from immediately saying, "this is a rip-off, please delete my forced clone"?
In general, Exit is a slippery type. Therefore, there is a possibility (just a possibility) that his nickname is also part of the "portrait."
