SimpleRefs, ProgramRefs, and TargetRefs...is three a crowd?

Tweet

GetRef is one of my all-time favorite methods of getting referrals. I'm pretty loyal to that site -- it's honestly one of the very few I've found that has an upgraded membership that is truly worth paying for. Still, GetRef isn't perfect. There are plenty of scammers there, and referrals from there often go inactive after getting credited for signing up to your programs (in my experience, though, most referrals are going to be inactive...building a downline is essentially a numbers game). Anyway, I decided to start checking out some of GetRef's competitors just to see if any would be worth using alongside GetRef. I discovered three sites that look very much alike: SimpleRefs, ProgramRefs, and TargetRefs. SimpleRefs and ProgramRefs seem to be run by the same guy; I'm not sure about TargetRefs. I like the basic interface that all the sites use, and I'm planning to give each one a try...but one thing is puzzling me. Why are so many referral sites being started up so soon after each other and perhaps by the same person? It seems that SimpleRefs is supposed to be a simpler version of ProgramRefs. TargetRefs' advantage is that it has the deepest referral program (five levels deep instead of three). If you use these sites, do you feel confident that they'll be around for the long haul? I always feel a bit uneasy when one site owner decides to start one new site after the other -- it creates the possibility that all the sites in the network could fail all at once which is really bad for those who have invested time and/or money into several! I'd hate to build a downline in one of these programs (or, worse, all three of them!) only to have the whole network collapse on me.
