This is a fraus kind of site. They will first call you a hundred times asking for you to register. Then they will spam your mailbox.
Even after you create your profile, they will not leave you and keep calling again. Finally, their phone execs are so shamelessly rude, that they will drop the call when you are speaking. I have deleted my profile from shine.com, and I wish there was a way we could register a case against these fraudsters for spamming the mailbox and calling so many times.
