u prolly use free proxy or so.
No, i dont use proxy.
I play only in my work and at home.
The problem can be with your work IP address. I experienced some problems as well when trying to claim some satoshi from the faucet from work.
It said that it was already claimed from my IP, even when I was alone at the office. I think it can be somehow connected with some security settings of the network.
It's a possibility.
But at the moment it does not work at work or at home.
I already restarted the moden from home, received a new IP, and remained locked.
something must be wrong in your side cause freebitcoin don't randomly block people , note that it's not allowed to have more than one account and this may be the problem in your case since you used it in your work
anyway they may not notice your post here so probably it's better to create a support ticket in their FAQ section
