I do not know shoebox and I am not familiar with his opinions but as I remember, he asked if he is allowed to write in the thread or he should not waste his time since it will be deleted. cbp answered that he could and then moved/deleted his post as soon as he posted. I think the following spamming was the result of his frustration. I don't in anyway support spamming or other childish act like it but I do not believe a moderator job is to delete opposing views either.

In this case I think it is both parties fault and to be fair, either both should be forgiven or if shoesbox is banned for spamming then the moderator statue should be taken away from cbp since he was as responsible as shoebox.

I believe the best course of action is to forgive both parties and instead try to encourage constractive discussion since banning people seldom solves any problem.
