You know the deal here, right?
On a piece of paper write:
Bruno + Current date + bitcointalk
Post it with your face visible in here. That will prove that we are dealing with the real Bruno. We can then move for the next whatever it will be.
Check his previous post, do you still believe he's Bruno?
Someone who just made us know about his countless favors can't be Bruno. He did a lot for the entire community but never asked anything in return, nor did he expressed such shit that this person just said. I won't believe this guy even if he does what you have asked him to do, and that's because I'm getting a strong feeling this old guy can't be him.
