Since you do not appear to be keeping up with the news, permit me to enlighten you.
By the NSA’s own recent admission, they do not know how many, nor which documents were taken by Snowden. This is due to both poor oversight of those accessing the data, we well as poor auditing of access to those same documents.
From this it is simple to conclude that they are also unable to know how many people are abusing the system. The articles you quoted only point to people the NSA is aware of. I would also point out some of those abuses occurred years ago and were only caught when the employees confessed, they were not caught by NSA auditing or oversight.
It would be foolish to think these few people that have faced discipline are the only ones abusing the records held by the NSA. The system appears to be far too easy to abuse, the oversight and auditing is near to nonexistent, and the sheer number of people with access to the data is enormous.
I am going to say with my belief that you are a shill and also possibly a fool to boot.
