I support a 100% fair contest, which means I also support allowing 1 posters to win. EVEN the one posters who aren't coming back, that's the nature of a fair pubic raffle. What counts is the exposure generated for the site. Anyone fan enough to run around to all the fan sites and sign into all the raffles for a chance are fan enough to do the beta good. (or whoever buys their code is fan enough, though not as smart. And much less evil.)
Equality of outcome is not the same as fairness.
There's "fair" in the sense of "I wasn't lied to or taken advantage of" but there's also "fair" in the sense of "What I get back is proportionate to what I've given." One is the fairness of honesty and the other is the fairness of just desserts. You can have both simultaneously, or neither, or just one or the other.
ZAM is in a position to give away beta keys mostly because of the users who drive the site by contributing either their ideas or their cash, or both. Some one who showed up and made a single post has done nothing, literally nothing, to "deserve" the same shot as those who have actually contributed. A 50 post scholar has contributed some thing. A 500 post sage has contributed more. A 5000 post guru has contributed a LOT. It's not unfair to reward them differently.
