I wouldn't call it a "trap," I think fairness and simplicity are perfectly reasonable goals to aspire to. It's just that in this case I have seen an abundance of evidence that people start to jump ship long before a max-fair judicial process starts to correct the course, so it is a highly unfortunate fact of the universe that a good captain must have an itchy trigger finger on the ban button with all the false positives and collateral damage that entails.
