I guess a significant difference is than 4chan is fully public. Whatever anyone says there can be observed by anyone and refuted by anyone. You can’t secretly slander anyone there.

What happened on the tea app were probably not knowable, observable or refutable for those actually being doxxed or slandered.

That isn’t me saying 4chan is absolutely morally in the clear, but it’s still quite a significant distinction.

The difference _for you_ is in the public or private nature.

It seems like your argument is based on (1) the discussion being slander (assumption); and (2) the idea that you could refute it if it were public (good luck, low credibility, also most men would immediately respond with vulgar name calling and - at least if anonymous - threats).
