were any of those sockpuppets or shitposts by you guys as the devs or anyone else in the know?
Nope! The only exception is probably the writer for Nerus, Roddorod, he's a friend of ours who knew what was going on. With that exception, no one knew about what was up with Argos. Some people just really liked him, and you can be sure we were laughing when those posts rolled in.
To be fair, I think there was a trend here. If you tricked Argos twice (with the contract and with the challenge of making a sacrifice) he becomes a lot more friendly and open. I think that a good deal of the posts you saw were coming from people who caught the implication that there could be a way to make him more decent.
Are there any parts you guys as the Devs (Nanoff and MinoAnon, since I haven't seen Awoo, Kangarube, or Nemo around, unless all of y'all sharing the main account in which case hi) would prefer to not be spelled out in such a summary because you'd like it to be a surprise later in the game for anyone who doesn't go down this route?
Not really. When the game released we put an embargo of sorts in the Mino Hotel Wiki for a week or two, which has already been lifted. As far as we are concerned people can talk about all of the Ruthless route with no restrictions. This includes the more revealing things about the narrator, if you want. In fact I think this will be a good thing, I'd like to see how people who played the Ruthless route discuss it with those who didn't.
Just please put a spoiler warning, as a matter of courtesy.
