There are no scams on this site. There is nothing misleading about it either. The only unethical thing going on here is the competition using the WOT site for their own ends. It's a shame when you feel the need to stoop this low.
Profit accumulator has a free trial, you can find out what it's all about for nothing, in fact, if you do the free trial, you will have made some money, not lost any.
Not sure why the original poster came the conclusion they did, clearly they performed no research into the system nor the site itself and just flagged it as Spam/Scam without any thought what so ever.
This is fantastic site and does exactly what it says. Its Matched Betting, there is plenty of information all over the web from much more trusted sources than this site, which can backup exactly what the system is, and no where has this ever been touted as a get rich quick scheme either.
I've used PA for years now, and certainly will not be stopping based on some miss informed review on a website which clearly hasn't done a single peice of research.
