+\item Another question for thinking like an attacker: Imagine
+ you have at home a broadband contract with TalkTalk. You
+ do not like their service and want to switch to Virgin,
+ say. The procedure between the Internet providers is
+ that you contact Virgin and set up a new contract and
+ they will automatically inform TalkTalk to terminate the
+ old contract. TalkTalk will then send you a letter to
+ confirm that you want to terminate. If they do not hear
+ from you, they will proceed with terminating the
+ contract and will request any outstanding cancellation
+ fees. Virgin on the other hand sends you a new router
+ and paperwork about the new contract. Obviously this way
+ of doing things is meant to make switching as convenient
+ as possible. Still can you imagine situations in which
+ this way of switching providers can cause you a lot of
+ headaches? For this consider that TalkTalk needs
+ approximately 14 days to reconnect you and might ask for
+ reconnection fees.
