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.
don't believe a single word on the main page of the site they write "WIN FREE BITCOINS EVERY HOUR!"and then block the account and say that you abuse, not figuring out who the bot is and who is not. It was a great PR for attracting users to their website. Now they ask to make a Deposit of $ 50-100 to prove that you are not a bot. they'll take the money and disappear.
