Hacking trophies?

[Jones man]

Hi all, I'm curious about hacking trophies on ps3? There's a site where you can buy trophies and platinums called platinum game services. I read reviews on them and they're all good. I'm curious though, would Sony know if I popped a trophy through them if it's one that isn't an online, or unobtainable trophy? I notice cod game lobby's on ps3 are full of hackers constantly so would they even care if someone popped a none online and obtainable trophy?
