Would you like to give an actual example of a subreddit you're banned from because you were posting in some other subreddit? Or evidence that that's happening to the average reddit user? I certainly believe it happens, but the times I've heard it come up was generally because of brigading and harassment from one subreddit towards another, which certainly sweeps up some folks who just happened to be posting on both, but feels reasonable enough, situation depending.
