I had a similar experience with a writer here. He didn't like my comment on his post so he reported my account. When I got a message from Medium referencing my comment on the writer's post I knew it had to be the writer so I blocked him.

It's pathetic how people report accounts for no good reason. If you don't like the writer or their opinion, then don't read them and ignore their comments. Or better still block the writer so you don’t see their stories.

Reporting a writer over trival matters is unfair because the writer has spent time, and resources to grow their account. I wish people could be more humane. I'm glad your are back. Welcome, my friend!
