Yes, it is easy if/when one has to do it. But deleting them doesn't mean they won't stop coming, so I said "don't". Now he knows I don't want to play "Let's PM each other because we don't get along". I felt uncomfortable PM'ing him especially after he promised he'd drop it all. I feel that to PM him would have only encouraged him. Enough said.
