What do you mean? This is suppose to be faucet site right? So why you guys blocked him just because he abuse the faucet, does not make a sense here. This is not suppose to be blocked since freebitco.in is abuse website, only on this site people can claim their faucet without scare being banned or blocked. Any reason towards this issue?
It means they claimed the faucet so much that it looked like a feat of endurance that only a bot could manage. Blocking those accounts is a way to find out if there is a human on the other end.
