That doesn&apos;t take away from the difficulty or cleverness of the hacks, but unlike the candy theft story, there is no acknowledgment that some of those things might have been unethical or illegal.&lt;p&gt;Edit: I now see the conclusion that notes the potential for illegality, but I feel like the body comes off as way too proud about aiding a scam of a business (the affiliate &quot;arbitrage&quot;)</text><parent_chain></parent_chain></comment><story><title>The Greatest Hacks of My Life</title><url>http://wesleytansey.com/the-10-greatest-hacks-of-my-life/</url><text></text></story>
