A lot of comments focus on how he was "harassed to death".
I see it differently. He cheated, didn't admit it when caught, continued to compete and cheat. This is a common situation. You either lose your reputation or continue to deny it and hope it goes away. Every time you cheat you hurt other people. People care about their little competitions, it's often significant part of their lives. If you come there and cheat hurt them. You continue hurting them every time you do it. You build your reputation at the cost of theirs. Courts/law enforcement are a useless avenue when it comes to cheating in sports or games. The only mechanism that works is reputation.

He deserved his reputation to be ruined, he deserved to be exposed and humiliated. He could have stopped it all by not competing anymore or you know, at least not cheating. His reputation was more important to him than his life. I respect the choice but it's only his. The community he tried to cheat employed the only defense mechanism that actually works.

You learn it's the only mechanism that works if you dealt with bullying, cheating at gambling, cheating in small business deals, cheating in sports, especially amateur ones. There is nothing else you can use to fight cheating/abuse. It's true the abuser often never admits wrongdoing until they are exposed publicly and humiliated. They hope it never gets to that point and they are often right. The same way the school bully doesn't face consequences, someone who stole something small from a friend doesn't or someone who cheated you in a poker game.

When they do get exposed they often blame their victims - true bully style. When I read the article I think about the victims. People who competed with him just so ego of a cheater could be satisfied and who beared the frustration of being helpless and officials ignoring their concerns for too long.

The article also mentions one of the most common and naive mistakes people make when accessing character:

"Everyone who knew him testified to his generosity, modesty, and sense of justice."

It's very easy and common for successful people to be generous and offer "sense of justice" to the community. I've seen this tens of times in the gambling world. You're successful, you are admired, you share your knowledge with others, help them, are asked to help when resolving disputes. You're well respected and feed of it. Then a day comes when things turn around. You either got caught cheating or the one edge you have becomes known and it's no longer there. Your results suffer and then it starts: you scam someone in a deal, you stop picking up calls from people who lend you money, you are suddenly involved in more and more shadiness.

It's just very difficult to judge someone's character when things are going well for them. Even violent drug dealer were often loved in their communities. It's just how people behave. It's easy, it's rewarding. It doesn't say much about your character.

It's a long rant about something I have dealt a lot with during my life from early years to adulthood. In business, in gambling, in sports, in little in group competitions for status. I know the community usually sides with the abuser/cheater. They are the popular one and it's just easier. He deserved his reputation to be ruined. For him it was more important than his life. Please don't blame the victims for his choices.
