I don't know what was your case, but mine is banned for sure, because I was my husband's referral, now it shows zero referrals in "refers" tab on his account.
You most likely logged into 2 accounts from the same IP address, that’s why you were banned.
You're wrong, you can generate new deposit addresses in freebitcoin. And as far as I know if you have multiple accounts on same device or same ip your account will be banned. But in my case, as you saw, I used the site with no issues for years. If someone creates multiple accounts, when they request for payouts they'll be compromised and banned altogether. I think my case is buying and selling big amounts of funtoken, they thought I hacked or misused something.
Yes, you can generate a new address, but the funds will still go to 1 account. I don't know what you did with the account. You can use it for many years and then suddenly get blocked. I can't answer this problem. I'm only sure that the movements on the first account were somehow unrealistic.
