I understand that you are an extremely busy man and I don't mean to bag on the owner of the site, but at the risk of getting hell-banned or massively down voted your response came across as being unhelpful and rude, if it had been someone else making the comment they would likely have been down voted for it, or at the very least treat with indignation and ignored.
Perhaps you didn't meant to come across this way and perhaps I'm in completely the wrong mindset about it, but such a short answer does nearly nothing to help the parent, you simply stated they had set off a trigger and gave no details as to why, what they could do in the future to prevent this or any kind of statistics or advice to aid them.
