from my conversations with them..and i'm pretty vague on the details is which since it's been a while ago..
Rockhardcash and Cashduck was a member of Dealbarbie
Dealbarbie was a member of Cashcrate and InstantProfitz and TreasureTroopers ..and I'm pretty sure so was CD and RHC.
Raidthebank was a moderator and still is a mod on InstantProfitz
Wild4cash, pocketcashgpt, instacashvault, sparestash, manderine's money (used to be owned by Manderine..now run by Dealbarbie's dad/sis), madmoneyforme, mooomoney, paycage,fairytaletreasures,lovemycash, allstarsmoney,dukeofdollars,discodollars, etc..
are all former members of dealbarbie if not, then those older GPTS.
sunshine rewards, I actually don't know but I'm pretty sure that it's not been around before dealbarbie, TT, IPz, or CC
