What is going on? Once is happenstance but twice starts to feel vindictive!
The simple answer is that I have no idea. I have not, repeat not, banned you Granama1. I wouldn't ban for 12 hrs anyway, I never ban anyone for less than 1,000 days. You say Again, has this happened previously and if so when?
I certainly haven't deleted any posts on the Listener thread. Now and again I have moved posts from the No Answers thread to the Answers thread if I have been made aware that the Answers thread is the best place for them. However, I've not done that recently.
