I can understand paying a fee to the pool you're mining at, but I don't know why anyone would want to pay a fee to the person who referred them.
Referral earnings are a normal thing in many industries, especially online.
@fsasa70: It is true to some extent that only minipool owners benefit.
However, all you have to do to increase your earnings is put a simple link in your signature. I earn 10-15% more in this pool than I do at any other, and I haven't been creating a bunch of threads and such, unlike some others.
People who do not want to refer anyone can still get the jackpot. Statistically, this will even out (since the jackpot comes from the fee you yourself pay) but it makes pooled mining a bit more exciting. The best thing about TripleMining (for me) is not the increased earnings, it is that it has made mining fun again. It's no longer just a matter of watching the BTC trickle in and then cashing out. Instead, I can now affect my earnings by referring people to TM, and I can hope to win the jackpot. The jackpot adds solo mining elements to pooled mining, and it really makes things a lot more fun. Not to mention all the great events they have at TM, constantly rewarding their members.
Even if you lose out in the end, it's worth it. Mining is no longer a monotonous, boring thing for me.
