I've been rolling around this idea in my head for a few days and thought I'd throw the idea out there and see if there's any interest.
There's a whole ton of poker sites on the B2B network (60+), and nearly all of them offer a refer-a-friend bonus. (Not all are available to US players, but at least +30 are). Some offer signup bonuses as well, but for the sake of this let's just focus on the refer-a-friend bonus.
If you use a current member of the site as your referral when signing up, you're eligible for a 25 euro (~$30) bonus, which is credited to your account after you accumulate 200 VIP points from play at the tables. You get 1 VIP point every time the pot reaches €7.00 and is raked €0.30 (that's for NL and PL games; for fixed limit the pot has to be €10.00), so long as you were dealt into the hand.
If you play 2-3 tables of 100 NL simultaneously, you can rack up the 200 VIPs in an hour or two. Ditto if you play fixed limit at 2/4 or higher. That's generally speaking, so your mileage may vary slightly. Lower limits take a little longer but you should be able to clear the 200 VIPs pretty quickly, regardless.
So that's $30 in your pocket for 2-3 hours of play. Given that the games are really soft, you should hopefully add a little profit.
On the other side of the equation, the referrer (the player whose username you used in the referral field when signing up) gets a 50 euro (~$60) bonus when you reach 200 VIPs.
Hypothetically speaking, the referrer could return some of that to you as an incentive. If they kick you back half of it back, you'd be making a $60 bonus for each site, for 2-3 hours of play. If you do 30 B2B sites, you'd be making $1,800, just in bonuses.
The kickback payment could be made to any number of poker sites that allow transfers between player accounts, or through Neteller as a last resort (due to the fees incolved for account to account transfers).
Speaking further hypothetically, the referrer could also arrange it as a contest, and set aside part of their money from the referral as an extra incentive. So maybe they'd set aside 5 euros from each signup and add it to a pool. The top three players who completed the most bonuses would get a piece of this pool, split up something like 60-30-10.
So if 10 players did this, for a total of 200 refer-a-friend bonuses completed, the player who completed the most bonuses would get an added bonus of 600 euros (60% of 1000 euros), second place would get an extra 300 euros, and third would get an extra 100 euros. That's on top of all the individual $60 bonuses for each site.
There'd be some details to work out but that's the general idea. It's slightly skeezy and money grubbin' but it's completely playing by the current rules for B2B refer-a-friend bonuses. It'd be a bit of a pain as far as administration and coordination but not terribly so. Most of it could easily be handled by email.
Hypothetically speaking, if you have any potential interest in such an endeavor, you could hypothetically shoot me an email at firstname.lastname@example.org with B2B in the subject line, and this could be discussed further, if there's enough interest in general.
Hypothetically speaking, of course.
