Now that it’s morning, I realize that the comment I was replying to wasn’t asking about itch.io’s registrar, but was actually a reply to a post by sureglymop.
Basically I didn’t notice the very slight indentation on my phone. Whoops.
I don’t know who sureglymop‘s registrar is. I’d encourage them to name and shame, refusing to refund is unacceptable.
How would you know whether Modified3019’s comment is factual and correct? sureglymop wrote “note: this was a different registrar than mentioned here”, and they haven’t written any other comments in the thread that might identify the registrar.
Update: Turns out GP simply replied to the wrong thread, so it was just a typical case of "downvoting takes less effort than pointing out a mistake", I suppose.
