Just read the Terms and Conditions instead of asking such a question. I can't believe you can't take the time to do it yourself and think other people are going to waste there time telling you. The only reason why wasted my own precious time is because I wanted to tell you off for being lazy!
I checked Vinefire but I cannot mark it as SCAM or NO SCAM unless I make some Bucks. But, who cares, if you are already making some bucks
It most likely is a scam but still, you can use it as free advertising and you can get results from that. So thats mainly what I use vinefire for.
