That looks like another faucet...
Listen, i'll try to explain this a little better, leaving out the technical parts, and simplifying (a lot) because to me, it looks like you're lost in the land of bitcoin (other members: i know not everything in this text is 100% correct, but i tryd to simplify it so much it was kinda hard to give all the technical details to)
You can compare bitcoin to a bank account number. The number is written into a database which tells you how much bitcoins are on the account.
In contrast to a bank, there is no central authority. You can make your own account number (bitcoin address). Because managing all your account numbers (and the private keys for these accounts) is a very complex task, a lot of people use "wallets".
These wallets actually generate all the account numbers for you, and keep track which numbers you own, and what the balance on these numbers is... They also manage all the technical stuff that needs to be done when you want to send bitcoins to somebody else.
You used a faucet to "earn" bitcoins... A faucet is basically a place where you enter your account number and do some basic task (like filling in a captcha). In return for this task, they send some coins over to your account... (they get their money by showing you advertising while you are doing the basic task)...
In your case: you showed us an account number, and said that somebody might have taking money from your account without your knowledge... Afterwards you started pointing to the faucet... BUT the faucet is just a spot that sends over bitcoins to your wallet. They have nothing to do with managing your addresses.. They don't have all your keys, so they cannot take your money, they can only send you money... If somebody took your money, it might have been a fault in your wallet, or maybe a virus that was evesdropping on your PC where your wallet was generated...
So, before we can help you, you need to remember which wallet you used to generate your address... We cannot help you if you don't know what you did exactly (i'm afraid)
Thanks for your help dude, because I have no idea where I generated this direction.
Already I say, I have account in blockchain and localbitcoins but they do not coincide with this.
Anyway I think that it is a mistake of mine since some addresses mark 5BTC like mine
