Legal ethics and social media

So you've just updated your status on Facebook informing your friends that you've been involved in a car accident. Moments later advertisements pop up on your screen offering the services of "where there's blame there's a claim" lawyers. You even get an unsolicited email trying to sell you a new car with all the latest safety features!

Is this kind of social media advertising and marketing ethical? The US Federal Trade Commission has published its latest guidelines on behavioural advertising based upon open disclosure and choice. What does these mean in legal terms for online advertisers using social media websites?

Lawyers Jonathan Armstrong and Eric Sinrod from Duane Morris LLP discuss their views in their latest Tech Law 10 transatlantic podcast.
