It looks like there is a scam within a scam - as in other opportunistic scammers are trying to set up a scam based on claiming Bitcoin Gold.
Check out this site claimbitcoin.gold - linked to from the "Bitcoin Gold" (@btcgpu) twitter account, but clearly a scam. It asks you to enter your private key or seed to "verify ownership" of the address you are claiming for lol.

That is incredible. Why is Twitter supporting a scam site?
Hi you, this is scam site.
You need check
1. site:
https://btcgpu.org/ 2. Twitter: @bitcoingold
This is most definately a scam, on one would ask for your private key, I mean absoultely no one !
I think this scam site is hosted by Namecheap.com and I've sent an abuse report to them, hopefully it will be down soon.
