+\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.
