Warning: Do Not Engage
You do know that tow companies and their practices are about as close to organized crime as you can get, don't you? Have you ever had your shit towed, and had to pay exorbitant extortion fees to get it back?
These people deserve it. They're blatantly saying "Fuck you" to the guy who warned them.
I would start filming yourself warning them as well in case they play the "we didn't know card".
Or honestly hire someone to come key all their doors, every day.
