What Does It Mean to Chat Anonymously?
To chat anonymously is to hold a conversation where the other person can't work out who you are, and ideally where you never had to register an identity to begin. Those are two separate layers. The first is about the stranger on the other end. The second is about the service in the middle.
Most people only care about the first layer, and that's fair. If you want to vent about your manager at 1 a.m., the risk you're managing is a coworker or an ex recognizing the story, not a data center somewhere. The second layer matters when you're shielding yourself from a specific person or organization. For that job a chat site is the wrong tool, and a resource like the EFF's Surveillance Self-Defense guide is a better starting point.
Anonymous also isn't the same as private. A private message goes to someone who knows you. An anonymous chat goes to someone who doesn't, and the point is that they never will unless you decide to tell them.
