Picture #2: The blue wire looks an awful lot like Cat-5, is it? Reminds me of an installtion a friend of mine was telling me about: He's a network admin. for his college. He "needed" an IG receptacle. He drove a ground rode (his version of IG) and then ran a whole bunch of parallel Cat-5 to the receptacle for his power wiring.
If the wiring in the picture is actually power wire, the only violation I see is the identification of the neutral. Unless there's something up with that ring-terminal on the EGC...?
Pic #1 doesnt look like they grounded the box or found a connector big enough to fit the hole on the back of that box they screwed to the wall.
Not sure about pic#2. The green tape on the wire nutted to the nuetral has me concerned. Seems like a wiring method changeover point, what is that blue wire?
Pic #3, you might have a problem getting a cover on it, with the circuit coming through the front. Of course, the cover screws are already being used for grounding, so they couldnt hold a cover anyway. Some of the white wires are going into black wire nut, so you have some identification issues.
