He speaks.

In an open letter to the media, “Leroy Stick,” the nome de Tweet allegedly behind the viciously satirical BP Twitter feed, finally lets us in on the big gag, explaining why he hijacked the oil giant’s brand in recent weeks. Why? Because he could.

I started @BPGlobalPR, because the oil spill had been going on for almost a month and all BP had to offer were bullshit PR statements. No solutions, no urgency, no sincerity, no nothing. That’s why I decided to relate to the public for them. I started off just making jokes at their expense with a few friends, but now it has turned into something of a movement. As I write this, we have 100,000 followers and counting. People are sharing billboards, music, graphic art, videos and most importantly information.

But while he clues us in on his motivation, we still don’t know much about who he is, robbing us of the full unmasking that the tech media has been craving in recent days. From the tone of the letter, “Leroy Stick” sounds more like an unemployed MBA than a hippy eco-warrior. The point of the whole brand-jacking masquerade, he tells us, was to punish BP for being so inauthentic and clumsy in its crisis PR response. Huh? Where is the concern for the dead pelicans, the devastation to the livelihood of the local fishermen, the ruination of Memorial Day weekend at the beach? More curiously, he concludes with the kind of call-to-arms you might hear at an Association of National Advertisers conference: He wants us to re-brand BP.

“Re-branding,” he reminds us, “doesn’t work if we don’t let it, so let’s hold BP’s feet to the fire. Let’s make them own up to and fix their mistakes NOW and most importantly, let’s make sure we don’t let them do this again.”

“Right now,” he continues, “PR is all about brand protection. All I’m suggesting is that we use that energy to work on human progression. Until then, I guess we’ve still got jokes.”

Am I the only one who wished he just stuck with the jokes? The “Leroy Stick” manifesto has Ad Age readers doing a bit of soul-searching, but I was hoping for something, I don’t know, bigger, something that goes beyond a message of branding, re-banding and the proper crisis management response. This will end up being the most devastating ecological catastrophe of our lifetime, after all. (Yes, I realize, I’m being a bit hypocritical here; many of my C-Tweet columns chide companies for their poor response to the public).

There is one very positive thing that “Leroy Stick” (if it really is “Leroy Stick” behind this BP parody) has done for us. Earlier this week I got a good chuckle over the latest @BPGlobalPR copycats: the savage @IsraelGlobalPR and @HamasGlobalPR feeds, both launched in the hours after Monday’s aid flotilla attack well out at sea somewhere off the coast of Gaza. Both feeds are at times obnoxious and offensive. But they work (in the humor category) because the surprising frankness of the delivery is so refreshing. It’s what we’d like to see more of from our elected officials, or from company execs for that matter. (Okay, maybe not Tweets like this one from the fictitious Hamas team: “Stupid israel, do u actually think we want turkish goods (& worse turks)? the italian ship, different story #gaza #flotilla,” but you get the idea.)

I’ve said in this space before that Twitter works so well as a communications medium because it’s so hard to insert PR fluff into a 140-character message. Twitter demands clarity and sincerity, the kind of qualities we’d like to see in all corporate and government communiques. There’s another thing Twitter offers: the ability to lampoon those who too frequently ignore those qualities. For them, to paraphrase a great marketing mind, “we’ve still go jokes.”
