Hello Medium Staff ... this is Fred

I don't know if you will be able to help me, but I seem to have acquired a problem:

When I opened my Medium home page today, I got this message - emblazoned on every one of my many, many articles and stories that I have successfully published over time:

"Your account was found in violation of the Medium Rules."

I cannot understand this, as there has never been any problem in the past - all my writing has been welcomed by everyone, and I make sure that it is of the highest quality and standard.

I am absolutely puzzled - I don't know what to do

Can you help me sort this out please?

Fred
