DFG, I think you are honest and straightforward and I don't see what you did wrong.
I know you probably won't want to say it - but I suspect this has been a bit upsetting for you. Suddenly finding yourself a mod, and then the next minute not. Made worse by the fact that there seems no logical explanation for these events.
If not upset, then fuckin bewildered at least! I am. Just don't let it affect your confidence.
I am surprised at Skyblue1 and even more surprised that Aspiemomma won't respond to your messages.
Don't dwell on it. You don't look bad. They do.
