Immature, unfair, and drama-whoring. But, doesn't look like there's anything you can do about it, unfortunately. If person X won't respond to your queries, there's unfortunately nothing you can do about it. Which sucks.

The people who know you will know that the offence you gave was unintentional. The others are jumping on a bandwagon.

None of which makes it any less frustrating. But hopefully, it's cooled down by now. Or will soon.
