I mean, any user should have had at least a few questions after the problems with spins, withdrawals, lack of draws for the 11th round of the Lambo lottery, etc.
I am prettey sure most of the freebitco users don't even know that they haven't done the round 11 of lambo lottery yet.
Most users don't care about that because they had a very low chance of winning or they just think that they haven't won the prize.
but if it really is true that withdrawals are made once a week, then it is very serious
It seems that withdrawals are sometimes delayed, but it's not that they are done once a week.
It's the auto payments that are done once a week and that's normal.
They should have changed their free bitcoin concept from hourly claim to a daily or a bit more a day if you "invest" in the site somehow, play there, complete some offers or anything else.
Do you believe that they can't afford to pay the free bitcoin people win through their faucet and that's why there are these issues with their service?
I highly doubt it. It takes a very long time people reach the minimum withdrawl limit if they only play the free rolls.
