Interesting post by The Pro on the forums:

As you know, people are suspended for offensive content in their bio, motto, or location.  Violators will receive a suspension, and the words “Code of Conduct” are entered in their profile.  After they serve a suspension, they get suspended again for what they believe is the exact same offense.

Gamer “Foo” places inappropriate content in his bio. (infraction #1)

Gamer “Foo” changes his bio, leaving inappropriate content in there, or placing additional inappropriate content in there. (infraction #2)

Gamer "Foo" receives a suspension notification for Infraction #1. (email includes offensive text)

Gamer "Foo" serves suspension #1.

Gamer "Foo" receives a suspension notification for Infraction #2.  (email includes offensive text)

Gamer "Foo" gets confused and associates both infractions with the previous suspension.

This doesn’t cover all possible scenarios, but it covers many of the suspensions that we have seen in recent history.  Each time you put offensive content in your bio, YOU WILL receive a suspension.  This isn't a case of "I wonder if they can see this...", we see it, and we take action. 
All posts regarding "I was suspended twice for the same thing!!" will be referred to this post.
