How faucet can be abused on a faucet site like freebitco.in?
You are an experienced faucet abuser so you don't really need me to tell you how you were doing it. But for everyone else what you did was sign up loads of accounts, make a few free rolls from each and then go all in on multiply BTC 3 times in a row to get above minimum withdrawal. Most of the accounts lose but you get to withdraw the few that win. When you found that I review withdrawals and block people that do that you tried making a very small deposit in one account that had won and then spamming a few meaningless bets to try and hide your tracks. I didn't work so now you are crying about it.
I saw it, but I mean adding this signature to website under "Refer" section where we have that very old basic signature code.
You can edit that code easily.
Ctrl+F
Then search for "178". (There are four "178" in the signature code.)
Replace all of them with your own referral code which can be found in "Refer" section.
I don't want to put the code on the site because it only works for Hero or Legendary Members. I would just get lots of Newbies complaining it didn't work. Anyone who has been on the forum long enough to use it would know to just send me a PM and ask for it.
