Interesting idea. Immediately I think of 4chan, where everyone used to be anonymous. On stacker you can do what used to be possible on 4chan, you can make a post, then log out and comment as @anon replying in support of your own post.

It would be a great improvement, after all, forensic linguistics is statistical, and linking one account is hard enough, let alone linking all texts, to some person. But not everyone wants to be anonymous. I'll think about this, thanks!
