I put the ‘To be really dissapointed in my brother’ thread into my Watching list this morning via Safari on my iPad.
This evening the thread had vanished from my Watching list.
I posted in AIBU to ask what had become of it. My thread was nuked as it was allegedly a thread-about-a-thread. Following my rap over the knuckles, the thread has re-appeared in in my Watching list with a note that MN are having a look behind the scenes, fair enough.
In the past, locked threads have always remained in my Watching list, not vanished and then re-appeared. It has not re-appeared in the Watching list on my iPhone which uses the App, however!
