People who make a thread where they sell a product, then they make 1 or more accounts to post in the same thread saying that they bought it, downloaded it, tried it out etc. It's so obvious sometimes.
Well, this is awful. I've heard that before but this is something that cannot be proved. And that makes it worse. But rest assured that people who have such bad behavior in their business will get to nowhere in the long term.
How are people like this one here still not banned. http://forums.digitalpoint.com/member.php?u=173268
Did you create this thread because you don't have any product for sale? I'm joiking. Well, people try to sell their stuff with any ways.
