Dispute a Temp ban

Ok so i had 5 infractions,i know i have to get banned for a period of time after a certain number of infractions,but my last infraction was "Signature violation"

The hell is that supposed to mean?
My sigs where "The i love fatih sig"
a sig made by humble pi
and a "The Spam Forum King has X Internets" sig.

Dont see anything that breaks the rules,PLZ REPLY.
