I'm sure there are a few, but chances are slim you'd find a full 8/8 ps4 static. Even then, what else are they going to be able use? Nothing..
As for harassment, you kind of sound like the government. "No one is going to tell us what their conversations are so we need to tap everyones phone and listen illegally" Lol. Parse police
I just threw out some ideas, doesn't mean it's the complete picture. A little imagination is necessary to find something that would work well and provide enough information to act on one way or the other, while respecting whatever hardware limitations are present with the console. I specifically mentioned it shouldn't try to replace existing 3rd party apps for PC. But right now there is nothing on ps4, so just about anything would be an improvement.
And just as an aside. ACT hasn't told our group one thing about why we are wiping in A3S, it can't correct human errors :P
