I believe the user is someone who was banned from the forum. Notice how they ask people to google "BitDice Scam". That leads straight to a website that is owned by the user game-protect. Of course it's my personal opinion and doesn't really prove anything but I strongly believe they're just ban evading and trying to get some traffic on their site.
If you are right, then that user behind this user is very famous across all of the threads. It says it helps people and yet, it has been involved in provable scams itself. They basically lure you in and make you think they are some kind of scam buster, then they ask you for money to pursue legal action which of course they never do. I suspect you are right too, also my personal opinion, but I see similar spam from all the threads:)
