Dear Vlad
Thank you for this valuable intelligence snippet, in which you reveal your current inability to identify Tor users. It has been noted. I guess there's an outside chance you're pulling a maneouvre, paying people to give the illusion that you can't identify Tor users, but I never credited you with an overabundance of brains or subtlety, so I doubt it.
Anyone fancy a Kickstarter to fund Tor development, with a target of twice his bounty? "Whatever he's paying you I'll double it."
