You're way off track. This has nothing to do with phone calls. There is a big difference vetween an anonymous phone allegation vs. links and hard copy that can be SEEN, on top of IT security evidence that tells an even biffer story.
I don;t know what is is you think is so special about hovt. People "call in" frivilous complaints to private business also. And believe it or not, some complaints about govt employees have merit.
But, as I said, this has NOTHING to do with phone calls.
