I don't know, to me it always seems to start with an account with a long name and man or woman in suits, carried on by people in similar online attire with extreme rage and confusion, until it hits someone with an ultrashort name and an anime icon who speaks shibboleth, at which point either the original misinformation is explained, or platform aristocracy kick in.

As far as my experience goes, those with full long names and professionally taken portraits as icons are easiest to trigger and corner because they only ever believe, refuse or double down. They never back down in embarrassment, or verify claims or make refutes with requisite care, and they are extremely angry by default as well. Complete anonymous posters(like in certain gray website) are very problematic in whole different ways but even those are not as easy to manipulate.
