That's what worries me - someone has appointed themself as the one who will decide who is and who is not to be blacklisted. This is not how we operate in a democracy. 50's when voluntary blacklists ruined the lives of many people. What is wrong with a blacklist is that it does not provide due process for those it indicts.
Indictment is equal to conviction.
There is no peer review, no hearing for the accused, none of the protections so important in our democratic society. I say no to blacklists. That's just not the right way to cure the problem. This is a fake email address. So many old members of this list were getting spam generated from siphons trolling the archives that I replaced all email addresses with randomly generated spam traps that forward mail to spam fighters.
