First try and convince people that you're an insider by cobbling together various rumours and acting like they came from you.
When people point out what you've got wrong quickly issue some "corrections".
When people still don't fall for it pretend you were doing it all for some high-minded reason.
Then claim to be someone you're not.
Like I said before, they're the GB poster that uses the name R.E.D. Not that it really matters, since paying them attention is what they want.
