Twitter X has been a flaming garbage dump for most of its life. The only thing visible at any given time is drama and outrage. Those looking for serious discourse and discussion fled long, long, long ago.
In the past I worked with severely mentally ill folks, and every so often you'd meet one who had a creative streak expressed with fecal "paints". I've also worked with folks with big, years-long drug addictions, and "explosive diarrhea out of nowhere" doesn't even begin to cover it.
Just walk away. In the "old" days we had to clean up stuff like that, but a decade or so ago they started requiring real hazmat response to anything that was wet - blood, excrement, vomit, indeterminate, etc. No one without medical quality gloves, face shield, and more should be interacting with anyone else's "stuff". Like I was taught in my last blood-born pathogens class: If it's wet and it's not yours, don't touch it.
