About triggering nullius with 1 word: with all due respect to all, I fully understand his reaction.

I myself am a man of principles and a perfectionist. I hardly support criticism and I only accept it when it is proved in an undeniable way that I'm wrong. Even for small matters, not to mention anymore the big ones. For example: if I see a tree, I say it's made from wood. Then someone comes and says it's made from iron. I try to demonstrate he is wrong. I explain that the tree can burn if it's wood; if it was an iron it wouldn't burn. I would put a magnet on it, which would fall down: because it is wood and not iron. And so on. Until I prove my point. The opposite is also true: if that guys can prove me, against all my beliefs, that I'm wrong, I'll accept it. Hardly, but I will accept.

People are "triggered" by various factors. Maybe nullius gets triggered by a false statement (no matter its importance, although in this very case it really is an important one) about him which he also proves to be false.

Reputation is essential, as I tried to explain here, fact stated also by Tim May: "Reputations will be of central importance, far more important in dealings than even the credit ratings of today".

Some people may get triggered by money, other by stress. Others get triggered by their reputation being affected in a negative way; even more, if the accusations are false. And far more if the accusations are serious. Dealings with underage children in such manner presented by ibminer may affect someone even more than by reputation: it's illegal. I think this is a very good reason for anyone to prove his / her innocence. Bad reputation is bad indeed, but being associated with such illegal things is way worst. One is to be avoided by people on a forum for having a bad reputation and something completely different is to be associated with CP, this implying also the possibility to be chased by Police.

From all the above mentioned aspects, I consider that nullius proceeded in a legit manner for defending his reputation. And, as he proved ibminer's statements to be false, it would be expected that ibminer would say "I'm sorry, I was wrong. And I'll correct my mistake. First of all, by apologizing".
