The blacklist isn't really much worse than the whitelist depending on the database... though if you're using a distributed/redundant db, such as Cassandra/Scylla, BigTable, Dynamo or Storage Tables, then a whitelist can be opportunistic.
If you're using a structured (SQL) database, either white or blacklist should work roughly equally.
