You're right, at least partially. There is one big difference between a site created for a certain group of people, out of boredom and out of wanting to become rich.

There's nothing wrong with neither one of them. We all want to help to someone, we all do certain things out of boredom, and we all want to become rich.

It's just that everything depends on the start, the way you do it. Someone can't be bothered to be nice to people, and some people have no ideas how to get members so they pick the bad side, the spam side. Which pretty much blacklists the online identity they used for spamming.
