It is going to be problematic to kick off someone who impersonates different users. What do you do, block IP numbers? We keep on saying that mailing list have worked this way for decades. Sure. And email in general has been working for decades before the need to use authentication arose. So we can bet that people using MLs is highly selected and well behaved... but is that true? Wouldn't a jester be able to completely disrupt our work by heavily repeating impersonations to the point that we'll be forced to restrict to Github tools to discuss our drafts? I wouldn't bet... Some time ago I proposed a p=mlm-validate[*] telling receivers to reject on failure only if they are a mailing list or similar forwarder. I thought that would cause minimal disruption since such kind of posts most of the times reach destination in one hop —akin to transactional stuff— and a poster who gets a bounce can quickly retry. Such kind of tool would eliminate impersonation chances. An obvious truth is that we cannot publish a successful protocol if we ourselves see no reason to make any use of it.
