What does this have to do with FUD? He just wants some anwsers. Blocking such a wallet is not helping at all. You should check your code for bugs that could have been exploited. Why should the hacker stop using his exploit just because you block the wallet? He will be able to get some free coins of this wallet before you can block it. If he automates this action he can make a shitload of coins, reducing the value of the "real" coins.
Stop blocking people just because their questions doesn't suit you! Provide some evidence for the actions you take and investigate the root of this problem. That's all you have to do to keep people quiet and not complaining.

I can only thank Rocket for pointing at such suspicious actions on the blockchain and I hope he won't stop until this is fixed!
