I recently posted a news item and took it down subsequently due to the nature of the guide after doing some more research about it.
I wanted to remind people that there will be an increase in scams - and not just ones that are through your e-mail. Third party publishers will be in full force to get in the market share for Diablo 3 guides. The guide I posted may end up being real, but many of these are false advertisements that are designed to get your money.
Like the one I saw being advertised, be aware of scams and faulty information on any unofficial channel.
If you have any personal experiences with scams that are cropping up, please post below so fellow users know what to look out for in the PMs, mail, and other shady retailers.
