If you consider "What makes what he did justified?" and "I'd say you're being incredibly generous" to be "blasting someone" then I hope you never have an opponent shouting at and threatening you.

I thought it was a valid question--I don't understand in the slightest how /u/SickBurnBro's suggestions would be at all a reasonable justification for the behavior described by the OP. If the opponent were misrepresenting the game state and otherwise attempting shady play, the judge certainly knows enough about the rules to call over whomever was judging the tournament while this judge played and explain it to them.

And in the event their opponent was cheating, a judge would know the recourse for that too, which (at least when I was a judge) involved DQing the offending player, and most certainly did not involve screaming, threatening, or falsifying the match slip.

/u/SickBurnBro did ask a very simple question, and /u/arkain123 asked a simple question in return about the thought process behind the first question. It seems like the question was well founded too; based on /u/SickBurnBro's response, he feels such a reaction would have been justified if the opponent were trying to cheat. It's valid to question the underlying assumptions here, because many people would feel that such actions would not justify the described behavior. There's a process in place to deal with cheaters, and a judge should know what that is better than anyone.

Asking a question of a question is hardly "blasting someone," and the idea that a judge yelling at and threatening a player is a justifiable response to cheating goes far beyond "being curious" and right into excusing overly aggressive behavior that would be inappropriate no matter what went down in the game.

Meanwhile, /u/SickBurnBro has apparently decided that a questioning of his thought process means that it's a "witch hunt," despite not a single attempt being made to ascertain any kind of identities (besides the guy who's investment firm is a massive Hasbro investor, and who probably has an uncle at Nintendo as well), and this comment thread itself is simply a response to the OP's question "how do you report a judge?" It's what the OP was looking for, it was provided, and everyone else is mostly sharing their own anecdotes of people flipping out. Hardly a witch hunt, nobody is being burned at the stake here, and nobody is being blasted for curiosity.
