I think so much of these types of actions stem from growing pains. It all stars with defining a policy (no assisted open knife ads!). You then have managers telling their employees to enforce it, but the TOS hasn't been updated and the front-line employees do not have the tools to really identify who is actively infringing. Once the front-line employees come back with dozens of complaints (or users complain), the management realizes the mistakes and things get righted. I'm sure it's no different for you - once you create the policy, you experience the problems implementing the policy that then force/cause you to create the tools/etc.
