You can charge your customers without indulging in shady practices. You just can't make obscene amount of money doing so. I remember when PoF was run out of some guy's basement. He was the only one (well, aside from a part-time systems support guy) running it, and he was banking $1M/month (he posted a photo of his check once) from ads.
