So basically, Bruce trolls chatrooms under multiple accounts.
Dick intentionally causes wank, lots and lots of wank.
Jason downloads everything, even stuff he hates, because REBEL AGAINST THE MAN.
Tim is a hardcore internet activist, Anonymous, Wikileaks, the works.
Damian and Steph trade cute pictures of kittens and are best friends online, having no idea who the other is.
Babs has given up on policing them.
My personal canon is that Damian holds the high score on Robot Unicorn Attack and Talia is a Tumblr addict.
Make of that what you will.
