I wish I'd found your post before trading with Milo2016 since he produced a bad situation with me as well.
After some initial confusion, he and I went through a successful round of trades. Because of this, I assumed he was trustworthy and sent him another video expecting him to reciprocate as he promised. He kept coming up with excuses for his delays in not sending the promised trade. Eventually, he stopped responding to my emails.
So beware of Milo2016.
