You… you told me once that you weren’t a hero. Umm, there were times I didn’t even think you were human, but let me tell you this: you were the best man, an’ the most human… human being that I’ve ever known, and no-one will ever convince me that you told me a lie. That’s so. There. I was so alone, and I owe you so much, but, please, there’s just one more thing, one more thing, one more miracle, Sherlock, for me. Don’t… be… dead. Would you, just for me, just stop it? Stop this.

So there are pictures of this bus ad going around and it directs you to www.stopmoriarty.tv. It’s a “global network of journalists and detectives” trying to stop super villains and you can become an informant. 

My theory is that it’s a new website the BBC constructed; maybe to lead up to the Special? Maybe the public will band together to find/take down Moriarty!
