Here is the (partial) official hard fork policy of freebitco.in
Bitcoin has 2 hard forks planned in the near future - "Bitcoin Gold" and "Bitcoin Segwit 2x". As we have done with the "Bitcoin Cash" hard fork in the past, we shall support withdrawals of all hard fork coins as long as they are viable - ie. have wallet support, a working blockchain and straightforward redemption policies. As "Bitcoin Gold" has announced a fork block number and has a wallet, we shall be able to make it available for withdrawals for our users. You do not need to do anything and you should be able to see an option to withdraw your "Bitcoin Gold" soon after the hard fork.
