I'm friends with Zach Jesse on Facebook, and this is what he had to say about the banning:

"I had not wanted to make any public statement on the issue of my suspension until I had a chance to mull over what had recently transpired. I had hoped that I could discuss Hasbro’s decision with them in an effort to perhaps temper their conclusion. Unfortunately, that doesn’t seem to be the possible any more. The cat is now out of the bag. This post serves to address the underlying factual information as to what transpired for those interested. On Tuesday afternoon, I received a phone call from a lawyer from Wizards of the Coast/Hasbro. I had not expected to receive any sort of communication from them considering I had not heard anything from either company after the whole “Drew Levin fiasco” or my recent success at GP Charlotte. I was told, in no uncertain terms, that my DCI account was suspended effective immediately and that I was forever banned from playing in sanctioned Magic events. When I asked as to what prompted them to reach this decision, they stated that they generally do not comment on the reasons for suspensions. When pressed, I was told that Wizards just “no longer wanted to do business with me.” I also was told that my Magic Online account had been frozen with the intention that it would be deleted. The reason for this decision was that my DCI account was linked to my MTGO account. I asked whether I could sell my collection or whether I could perhaps donate the cards in my collection to my friends’ accounts. I was told that I would not be allowed onto my account again. I’ll note here that I hesitate to say their answer was a hard “no” as to whether selling or donating was an option—there was some suggestion that maybe an agreement could be reached in this regard—but that I would 100% not have the ability to sell the cards piecemeal. When I asked whether I could start a new account, I was told that to do so would be fraud, and that any account I created would be deleted. I was told that they would do an inventory of the collection. They would use this data to form the basis for an amount that they would give me in good faith in exchange for my account. It was stressed, however, that they had an unfettered right to simply not provide me any sort of compensation whatsoever, if they chose. To their credit, they have made me an offer that does not sound entirely unreasonable. My collection dates back to 2005, however, and so I have very little concept of what is actually in the account. They have provided me a list of my collection although I have not had an opportunity to read this manifest, so I do not know whether their “offer” is in fact good or not. I tried to reach some sort of compromise with them, particularly with regard to maintaining my ability to play Magic Online. I explained that I recently accepted a position where I was tasked with writing articles and produce videos on Magic: the Gathering. They have not changed their stance. All of this has transpired in the last 48 hours. I really do not know to what extent I intend to answer questions on the subject, whether I’ll say anything further publically, or whether I’ll consider any other action. I’m not going to promote discussion of this topic, nor am I going to caution people from talking about it. Do what you’d like. Perhaps this change is serendipitous. I now have oodles of free time that I otherwise did not have before. I had plans to play in the MOCS this Saturday. Perhaps I’ll hang out with some friends instead."
