This was what I was thinking. If she put quotes around "thank" and used unceremoniously instead, the post would read closer to what it sounds like she intended.
Edit: I only just noticed a couple of things: first, this post is five years old. Second, she responded with full-throated support of Rick. So despite the fact that he is pretty well understood as a POS around most Trek communities these days, Denise doesn't seem to want to be lumped in with that.
Ceremoniously makes sense. You’re doing something you know is wrong so you play it up so no one will stop you, or they’ll be interrupting a grand gesture of sorts when they do so you can play the part of flustered surprise.
