Over the past few days on here, some new members have been posting about a new fork of Stellar which is called Stellar Dolphin. These threads have since been removed.
From now on anybody that tries to promote this hard fork on here will be banned. There are a number of reasons for this:
They ask for your private key to claim your new coins. This is never, ever a good idea.
Nobody knows who's behind the project which doesn't give you much confidence in it, especially when they are asking for your private keys.
Here on Stellar Community I always make sure that scammers don't use this forum as a way to promote their scams, and this one just isn't worth allowing to be on the forum. It's very shady.
Thanks :)
