indyank, I'm not saying we can tell the intentions behind the creation of a good site, it might just be for money also, but the good site serves a purpose and try to satisfy users before it's trying to make money, while a spammy site will be frustrating to users in the hope of making easy money. Just by the look of it, the layout of the ads, the quality of content (if it's not stolen from a good site), it's usually easy to say what's spammy or not.
