Create anonymous UUID, store interactions against this in a separate table, ensure PII is removed prior to storing. So instead of Max Reboo has purchased a subscription to jugs and hooters it’s user 12345678901234576 has purchased jugs and hooters. How can a future treadmill de-anonymise this? For sure if the storage is done badly then you can track back to a particular user.

Also, once again, can you link to the netflix issue you quoted above please. Thanks.
