Copied from another thread that I responded to.
We have detections in place for players that do this, and deal with them appropriately. This player and the groups specifically we were already aware of; just know that these things aren't instant, we want to validate anyone caught manipulating ranked to reduce false positives.
Definitely frustrating, but it's easy to see when people are doing this and take action. We understand that this is a bi-product of 5 stacks rules(which we think are worth the cost), and we are only going to get better at preventing it and detecting it. Hope you are having a good first week of the Act otherwise!
