I was subscribed to his newsletter a couple of years ago. First I was pretty understanding about his emails (he was asking for money etc.) because he said he's had mental health problems. Then I started getting emails basically every day and had enough. I unsubscribed but the emails kept coming. I did it a few more times and they mostly stopped, but he still sends them when he feels like it. Looks like he's activated my address again and I've got 3 this month. I mark them as spam now. Very unprofessional.
