The website below claims to redeem your bitcoin diamon if you paste your 12 word seed. Not sure if this is legit or not.
It's definitely a scam and you should take away the link from the OP so that somebody does not click on it and accidentally use it and lose money as a result. All of these forks have led to these scams happening, since a lot of people don't know what to do to get their share from the forked coins.
This is why you always, always wait until the official people from their development team comes out with something, that way you know it is secure.
Never ever trust any "claiming" services with your private key, unless they are really trusted and you have cleared out your address of all BTC balances.
