I've only hacked on facebook and neo :p
I wouldn't call it hacking but I've got access to people email's and facebooks through information available either from their profiles or freely available. I also do a bit of social engineering on occasion which is sometimes referred to as 'life-hacking'
Facebook,Neopets,xbox live, and minecraft accounts
i giggle when i get the password to deviant art. I mean you could reallllllllly mess up some ones commisions, but im not that mean.
Umm many but some facebook games, adventure quest and bots acclaim when it was still around.
I hacked every game I have ever played.
