Well, it can be legally punished true, however, it wont' So far I have never seen a single case where this happened. It is required to use your brain when using darks and it is required that you consider and plan where to open accounts or whatever you have in your mind to do with the darks.
Some people are just using these documents without to think about what they are doing and they face problems, most often they siomply get rejected or can't get anything approved because they fail to do things right. But that said, I have not heard anyone that got legal troubles.
