There are plenty of services that are paid and not set up in your best interestes (Profit Accumulator is the most popular these days).<p>If you&#x27;re interested I highly recommend the MoneySavingExpert Matched Betting forum - <a href="http:&#x2F;&#x2F;forums.moneysavingexpert.com&#x2F;forumdisplay.php?f=41" rel="nofollow">http:&#x2F;&#x2F;forums.moneysavingexpert.com&#x2F;forumdisplay.php?f=41</a><p>It is free, unbiased (lots of the specifically tailored sites like PA mentioned above have affiliate deals which reduce the amount you can earn) and active.<p>Discussion on the MSE forum is restricted to what they define strictly as &quot;risk free&quot;, not &quot;EV+&quot; opportunities, but that&#x27;s a healthy start.<p>Their definition of risk free is making a guaranteed profit regardless of the outcome - Either natural arbitrage or an offer-dependent forced arbitrage.
