OK, because I'm an ehrliches Schwein, and I'm home now on a different device -- yes, hitting Leave will (eventually) delete the PM. I wondered if it was cached somewhere on my phone, but because I'm a bit hazy as to where the cache is and don't know an easy way to hard refresh equivalent to Ctrl+F5, I couldn't do anything better than turn it off and on again, but I could still see Pacifica's test PM.
It's gone now, from both devices. So I was wrong, but I'm admitting it, because although I hate as much as any unehrliches Schwein to be wrong, not admitting it won't actually change anything. Do you know, I never even noticed the Leave button before this. If Godmy did what is free to every member to do, there's nothing to object to. Weird, though.
However, there doesn't affect the legitimacy of the other issues, which nobody has addressed. Why was my non-serious thread in Feedback locked for not keeping to the topic that it didn't have? Why has this very thread been moved from Feedback, where it made sense, to this forum, which didn't exist at the time I started the thread, and where it clearly doesn't belong?
