Sadly, emmausa, adamusa, and karausa seem to be bots. I'm pretty sure they're powered by the current variety of chatbot / "AI", scraping the forum to give a response that looks superficially realistic. Another example
on the fanfic forum last month embarassed itself by attempting to copy the style of the thread it was in... only to discover that there was only one post, so it just blatantly reworked that and called it good. It even snuck a link into its quote of Mithadan, which I'm sure it thought was very clever and sneaky!
