Comment on A New Clone of OMICS Publishing Group: MedCrave by Juan carlos sosa

Is there anyone that has actually published something with group?
My question is: if this journal is neither indexed in pubmed nor in the open access journal directory: is it worth publishing (consider there is a 600 dollar fee)
The payment of this fee is through a “donation” Is this the same mechanism for other more serious journals?
I am really trying to find out if this is a scam or is for real. thank you!
