Great for delivering a most scathingly ad hominem attack on some deserving public figure (which'll get you into jail normally)?
Why wait?
The immediate thought that occurs is "how will they know you're dead?". Obvious: someone has to tell them. Next thought: "how do they know who you are?". Obvious: you have to tell them.
So set up the app with an entirely fictitious person and then report their death. All the company can do is point to an apparently dead customer. (Point of order - should this be an ex-customer?)
