One of the most common types of bullying in the US is the use of zero tolerance anti bullying rules as a mechanism for bullying.

Example: kid A punches kid B. Then immediately kid A reports kid B for bullying him because kid A knows how the bullying rules work (because they are a bully). Then kid B gets in trouble for getting bullied.

Typically kid A's parents will enthusiastically back then too because their kid "gets bullied all the time" while kid Bs parents aren't experienced with the policies and aren't positive that their kid didn't do something wrong (because they are normal parents), so they don't fight it too hard and just want it to go away.

Ask any teacher in the US and they will tell you that they see this all the time and most every kid that supposedly "gets bullied all the time" is doing exactly this.
