Talking about this like there's an "attack" feels very melodramatic. It seems to me like the non-constructive messages are either shitposts or just curious probes (testing whether certain codepoints make it through, testing whether bad no-no words make it through, testing how various things will render, testing whether the input is sanitized...). There's links to God knows what and some walls of inflammatory language, but I'm not noticing anything that could even remotely cause any harm.

It’s a blog post written by AI. AI makes everything ponderously dramatic.
