FA Exchange

Are those thieves? https://www.faexchange.com/
I have created a balance of BTC with them and they now request to pay taxes in order to be able to withdraw my profit so I am worried about and wonder why they do no keep the taxes from my earnings?

Additionally to report that they do not allow any withdrawal until they receive the taxes however I have found out that they are included at "bad list" https://badbitcoin.org/thebadlist/index.htm
Any kind of advice on how to continue further on to casah/ redeem my Bitcoin would be usable
