We've discussed this subject before, and basically, the consensus is that if enough people complain, the moderators act on the complaints. Apparently, the moderators got enough complaints about UF_Pike to take action, but not enough people complained about that post of Tom's . . . not surprising, since it's pretty tough to make sense of his posts half the time anyway.
Besides, one post of Tom's is hardly equivalent to countless posts of UF_Pike's which have been offensive to minorities and women.
