You are not alone in experiencing this bug. Here’s a link to my post in case you’d like to read more about this issue: The Competitive Bugs Megathread. I put your thread under: Competitive Match Disconnection And Ban. Please help in spreading the word about this megathread and other related threads regarding these issues.
Could you provide the link for that video? If that really is true, then it’s ridiculous that the Devs can’t implement that system capacity for the rest of us regular players too. We need to complain more on the forums and get them to implement that for everyone who was unfairly penalized for these system bugs.
