Thomas I promise its my last post in this thread.
First, technically you’re correct there’s no written rule describing sandbagger. But apart from written rules there’s a common sense. And no one wants to race against riders like you - gaming the system to your satisfaction - simultaneously ruining the experience for all other riders. You got caught, and that’s it.
Second, Zwift is a freaking game. There are no “angry mobs” and “witch hunts” here. Use the words you understand.
And third and most important. If you race in C you are a sandbagger, rules or no rules. You will be occasionally called out. But there’s very simple solution to get rid of this tag. Ride in B. Voila! Magic! One simple move and no controversies anymore!
You are legit B rider, ride where you belong.
