Re: How long before the courts move into the modern world?
If you think the scam of emailing to a target to change the bank account number they're paying their builder on is new, then you haven't been around long
Yes. What electronic communication has done is lower the unit cost of sending malicious messages, and the cost of discovering potential recipients.
Of course this fits a broader trend of decreasing cost of communication, benign or otherwise, that goes back centuries. Eisenstein's The Printing Revolution in Early Modern Europe is a good, if dry, survey of the process in Europe for the early modern era (as you may have guessed), and Yates's Control Through Communication is an engaging look at it in the US from 1850 to 1920, when many key innovations happened.
