It's not really typical from what I've seen. Most of the shills/sockpuppets just post one or two lines and can't avoid making obvious grammatical errors even then. This Rias guy seems to be somewhat different. I have no idea what his connection to bytecoin/cryptonote might be if any but he's not a run-of-the-mill shill.

I will say that a while back Rias asked me if I was part of bytecoin, which is a bit of a laugh, but you would think if he were part of bytecoin he would know whether or not I was. Of course, one can imagine all sorts of spy-vs-spy theories like that he asked me just to make me think that he wasn't part of bytecoin, etc. But I actually don't think he's one of them, probably just someone who was intrigued early on and got involved. I do agree the line up of dates, etc. between Rias and DStrange is odd, but I'm not totally convinced by this part of the story.
