I'm noticing a large number of people are sorta separated on this issue, mostly in the stance that "They arrested a potential predator, therefore the ends justify the means."
To those of you that think this, I'm afraid that's not how this works. While it's true that there were plenty of reasons to book this guy, the way they found out is fundamentally unjustified. The only reason it's overlooked is because they genuinely lucked out this one time. And ultimately, it should be a separate case from his game design accusation.
The fact that the game design and his real world discrepancies are conflated to be in the same category is beyond wild. The only thing authorities did wrong is base this investigation off of a dude fantasizing. That's enough to put someone on maybe a list if done inappropriately, especially in a public setting, but this wasn't that.
The bigger issue here is that we are taking an isolated incident and having it validate every wrongful prosecution that's happened before and after. You're essentially saying "It's fine if we arrest 1000 innocents so long as we catch one real predator." That's what's known as a "Scorched-Earth Policy", and as we all know, that helps no one. Ever. Crusades, Witch Trials, Hays Code, Prohibition; these have all manifested violence and death in ways we couldn't have even dreamed throughout the centuries, and they all had the same mentality as this process.
