When you say that you have discovered that this person also uses these other IPs, what do you base that on?  Further, if indeed this is as you propose, then it's really a job for an administrator, not us.  And, the policy is not to provide additional warnings, and in particular not to provide an escalation of warnings, unless the user has had a chance to read and understand the previous warnings. In your admirable haste to uphold policy, you appear to have (unintentionally, I am sure) overlooked and violated some policies yourself.  (Incidentally, I'm well aware of the need for citations and the need to keep plot summaries brief, though thank you for the reminder).
