SYMPTOMS OF EXPLOITABLE SYSTEMS.

================================================
 * Vague definitions
 ------------------------------------------------
 (wiki: London congestion charge)

 In 2007 a green motoring website alleged to TfL that owners
 of luxury cars were registering their vehicles as minicabs
 to qualify for exemption from the charge. Registering a
 vehicle as a minicab costs £82 plus £27 per year licence
 fee, much less than the congestion charge.

 In India, the office of the President is merely a
 constitutional body with minimal, or no powers.

 However, the President has a power called Pocket Veto.
 When a bill has been passed by the Parliament, it has to be
 signed by the President to become an act. The President can
 sign or send it back to the houses for revision. If passed
 again (with or without revision), the President has to sign
 it and it becomes an act. So, says the Constitution.

 However, the Consitution doesn't specify the time frame for
 this process.

 So, when The Parliament passed The Indian Post Office (
 Amendment) Bill to President Giani Zail Singh, he used
 Pocket Veto to hold the bill [forever] until the end of his
 presidency.

 By that time, the government already changed and revised
 the bill, removing the bits about being able to read
 personal correspondence of every citizen.

 There are historical examples, where the value of the
 lottery prize vastly exceeded the combined cost of the
 tickets. See http://www.futilitycloset.com/2011/09/04/easy-money-2/

 * Legal mistakes

 (wiki: Principality of Hutt River)

 "In correspondence with the Governor-General's office,
 Casley was inadvertently addressed as the "Administrator of
 the Hutt River Province" which was claimed (via Royal
 Prerogative as the Queen's representative) to be a legally
 binding recognition."

 * Arrogance of the opponents
 (One needs to understand the system much better
 than its average user)

 In 2008, Alexeyev received a credit card application from
 Tinkoff Credit Systems. The man filled in the contract and
 sent it back to the bank but with changes that he had made
 himself.
