It&#x27;s an excellent example of the middleman that only extracts money from a system, that adds no value to the system.<p>They insert themselves into the transactions where they can siphon off very small amounts of money over a very large number of transactions.  Nobody benefits but them from what they&#x27;re doing, no one walks away with something in their hands or brains by their actions.<p>It&#x27;s legal, but it isn&#x27;t right or a good thing.
