You would be surprised how much of what you do is monitored, i'm not sure if it's as abundant for Australia but in the USA pretty much everything you do is watched. Ever since most deepweb terrorism sites are being caught and shut down, they've found ways of doing illegal activity in places that are less likely to be caught. A while back, there were terrorism plots being made in private chat in through Runescape, yes fucking Runescape, they were caught but i'm not sure about what they are up to nowadays. Thing is, everything is being watched. Even this message, so if you're reading this CIA, hello and stop fucking spying on me.
