Aside from FruitBasket there is really no one defending CryptoSharks on the services he is offering so I wouldn't give too much weight on him since he is only one person which can't be proven reliable. It's obvious that only one person is saving his ass that it can only mean they are either working together or FruitBasket is paid to save him, I don't see how only one person is giving him a good feedback when he claims that he has a good trading both that provides "guaranteed returns" to its users.
