I had a similar neighbor that made my life miserable but what I did was collect all those “blow-in” subscription cards from the newstand and fill them out with his name and address. I then got to watch the mailman bring all these unwanted magazines to the house day after day. Must have been a major pain in the neck to get all those subscriptions cancelled, not to mention all the explaining that had to be done.
What a coincidence! All my neighbors with Obama bumper stickers recently subscribed to Newsweek and the Boston Globe. Funny how that happened.
