user48884: The creators of Bitcoin Gold claim that they have implemented full replay protection. How does this replay protection work?

user51948: I don't believe any replay protection has yet been implemented, they still have an issue open for it on the BitcoinGold repository here:
https://github.com/BTCGPU/BTCGPU/issues/51
I haven't dug into the code itself but I would imagine that they would have closed the issue if they had implemented something.
The statement by Bittrex also claims that they haven't implemented any replay protection: https://support.bittrex.com/hc/en-us/articles/115002320451-Statement-on-Bitcoin-Gold-BTG-
Update as of 3rd November 17:
