::::::Tom  As I indicated above, self-published information should never be used as a third-party source about another living person. You agree, do you not?  
 ::::::The rule isn't limited to personal attacks. Though on top of the breach of the rule, we do have that here, which exacerbates the violation.  Clearly, the existing use violates the rule. As it consists of Leiter's personal self-published blog being used as a third party source about living people. The use of it not only "about" other living people, but to attack other living people, simply is exacerbating background. And it is irrelevant to the point that the use violates the rule, since the rule is clearly already  violated whether the material is an attack or not. But if for some reason you want to focus on the attacks  yes, saying someone is not good at their job is no doubt a personal attack, as I use the phrase  it need not be limited to corporeal matters such as: "you have an ugly face".  
 ::::::Surely, you do agree that these are personal blogs used as third-party sources about other living persons, and hence violate the rule against such use. That's all that relevant.
