I am puzzled seeing anyone here can give more then single star, and I sincerely doubt authenticity of the positive reviews.
I was notified I got message from old friend. I was asked to provide access to google account just so that I could see message. They also asked for permission to contact my contacts (that I refused - if any of the contacts is contacted, would follow up with all appropriate government/police agencies as it is illegal in jurisdiction I am in to contact them after I refused permision).
They also asked for DOB and photograph (by which time I made sure I am not providing them).
And then they start spamming with inappropriate material (mostly pictures of young woman). I tried to both unsubscribe and report spam (provided in their link), they ignored both and continued sending mails.
At that point, I reported them to US and HK government agencies.
Stay away!
