@bryanlunduke @msh Not easy at all, but perhaps helpful: When talking is limited to one discussion and the account with false arguments could get the chance of returning and not doing some kind of "stalking" - had this on #Diaspora with pamphlets and insinuations - there could be a chance. You could evaluate the situation within the next days: Calling out an argument #antisemitic could help, because the person behind the account got the chance to think about.
