Let’s say you’re an individual who wants to start engaging in naughty behavior online but the Ashley Madison dump has made you skittish. Engaging in bad behavior (and for that matter crime) is pretty easy in the grand scheme of things. Getting away with that behavior is actually pretty hard. To get away with it you have to get everything correct in a way that can’t be mapped back to you and even seasoned cybercriminals get this wrong from time to time.
The key is making sure no attributes of what you are doing can be mapped to your actual persona. Josh Duggar was caught using Ashley Madison (as were others) because they used their real names and addresses. This is not a difficult problem to get around if you use gift cards to purchase subscriptions as many people did. It also creates the possibility of using another name altogether.
