Pickman's model
Starry Wisdom
the people i can think had the undesirability of their presence communicated to them in no uncertain terms, but as TopCat says, this wasn't done through 'official channels' but by what i'd characterise as informal means and tc would call threats of violence. people like fascists and so forth, generally not people who were anarchists of any stripe ime - but i'm thinking of the 1990s, maybe early 2000s.So there is some sort of precedent for "banning" the leafleter (was it just one leafleter or were there more?) and members of the mob (those who could be identified anyway) who attacked her.
