The answer very easy - they are cheaters. It explaines everything. They spend 1-2 hours to make site(that`s why it is awful), then creating a thread like this and cope-paste it for different boards. Then create the same site and repeat it all. If even 5-10 men will spent $10 - it will be enough to repeat it again and again.
I would second to that. I think that this people are thinking ahead of themselves. Maybe they thought that forum users here are gullible enough to just fall to their bait, which is clearly a proof of mediocracy when it comes to thinking of ways to do such intention. I mean we have seen far more scam projects that have done so much, and even that was revealed and busted, so what makes them think that attempts like this will be pushed right?
