It's sortof like guilt by association and not far off from credit reporting. I don't know what the current count is but some bot detection software and appliances can use upwards of 80+ indicators. There is incentive is in positive detection but there is little incentive to remove entries to avoid false positives currently. One can see the end results wake of pain it causes by comments here of people having accounts terminated for no obvious reason and being cut off from all corporate communications. Financial systems are hyper-vigilant in this area.
