Very innovative protest action - genuis! : )

And here is the story of the guy behind it:

"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.

Why has this caught on?  I think it’s because people can smell the bullshit and sometimes laughing at it feels better than getting angry or depressed over it.  At the very least, it’s a welcome break from that routine.  The reason @BPGlobalPR continues to grow is because BP continues to spew their bullshit."
