You said you made 150k free rolls, but that's just impossible since freebitcoin only allows 1 free roll per hour. Even if you pressed the roll button 24 times a day, it would take you 17 years to claim free sats 150k times. It's funny because freebitcoin was only launched 10 years ago.
The user hasn't said anything about the number of accounts he has. Maybe he is claiming the hourly free faucet with at least 10 accounts. It won't take a lot of years to make 150k free rolls if someone use several accounts to claim the faucets. He had said this here a few weeks ago.
they scammed me and did not let me withdraw
Freebitco team only block the withdrawal of abusers. Either the user is a liar, or he is an abuser.
