One of my guildmates plays using a console controller, which is supported by Blizzard natively in Shadowlands. She uses an addon called ConsolePort to make this doable in Classic. A few minutes ago she was disconnected while playing with her husband, and recied a notice that she has a six-month ban for botting. We think she somehow got flagged for botting. Blizzard, this requires a fix. Everyone else who plays with a controller for accessibility reasons - BEWARE
Instead of hyperbole, let the appeal process work for your friend. From what I am seeing on the CS forums, a lot of the suspensions are being overturned.
