Blacklist operator turns out to be listing instances for seemingly arbitrary reasons. In other words, water found to be wet...
"We're starting a telegram chat to share information on bad people"
"We're sharing their PII around because people should know how awful this guy is"
"Hey, they listed my boyfriend as a transphobe, he's not a transphobe... but he did argue with the blacklist operator that one time..."
Seen it a million times, always goes the same way.
