It was very kind of you to help Sadie to answer my question. I do wonder how you seemed to know exactly what she was referring to, however. I didn't. Or was it just a lucky guess? Perhaps she'll answer for herself in her own good time.
Once again, your ability to understand simple English seems to have deserted you.
I initially wrote:
“I expect Sadie means by PM, which enables people to complain about and discuss others’ behind their backs. Were you unaware of this facility.”
Since that post you have repeatedly avoided answering my question, just as you repeatedly avoid answering any of my questions. I can only surmise from this that you find my questions far too challenging to answer honestly.
There is only one “backdoor route” on any forum and that is via PM, unless you think Sadie meant someone opened an actual backdoor to go and meet a member of the moderation team in their home?
What I don’t like are your sneering attempts at mocking Sadie. Bad form for a moderator IMO.
