I purchased a method from this user at start of this year (end of january), and the method he sold me was proven to be a public method. I asked him for a refund and I had even been in contact with admins about it. It took him 2 weeks to refund my money. Now I see this thread and I told him I'm interested in buying this, but due to our previous history I now am asking for a MM.
His response to this is that using a MM is bullshit. You can see part of our conversation here:http://prntscr.com/v381j6
I am not saying this guy is a scammer but I urge everyone to deal with caution. If you're looking to buy atleast ask for a MM. He might use one with you. But judging by his hostile & negative attitude I wouldn't recommend dealing with him at all.
