Board Game Arena

Just had the most bizarre experience. Was playing a game of sea salt and my opponent hit stop on the first round with only 7 points. I opined in the chat that this was a weak move in the first round and they told me to get therapy. When I protested that this was a mean spirited response to a friendly observation, they accused me of having "insinuated" that their mother was a "c word" and then quit the game. They posted a random jumble of letters from a previous interaction that I'd sent by complete accident, which they had decided was some sort of obscene acronym.

Has anyone else experienced this player and their bizarre behaviour?
