Regarding refs. Refs don't get deleted, cookies remain for 6 months in everyone's browsers.
Accounts which enter the site and don't come back after 6 hours (are treated as guest/non registered accounts) get wiped from the system, so I can keep the database clean. If user registers, and plays, he's got 30 days until his (balance only) get returned to the wallet, so other users can benefit from it. Sleeping money is the worst thing in an economy.
Now, in case you don't login for 30-XXXX days and you've at least got 1 satoshi credited by anyone down your downline, it'll "ping" the system and let it know that you're contributing and it wont touch your earnings/balance.
Feel free to drop me a PM if you got any other questions, glad to help
Thanks for the prompt response! Things have been going quite well on my end, but I'm so swamped with all my non bitcoin related clients I haven't had a ton of time to work on my bitcoin projects. Lots of late nights over here for me!
I guess my problem is that I'm under the impression that if I can't login every 30 days reliably and any balance I have gets wiped it's impossible for me to profitable with referrals. I'll send you a PM though so we can take this discussion out of this thread, as I am still not fully understanding how it all works on your sites. Thanks again!
