I lend a hand on the unofficial API discord and I’ve had this question a few times in PMs and I don’t how to answer, I’m hoping a blue can give me an idea so I can disseminate (and link to this forum post).
How is historical data handled under the new data protection policies? I’m aware full profile data is expected to be deleted if not refreshed, but I think this example is slightly more specific.
Eg. WoWProgress has guild history, knowing what guild you used to be in would have been through an API query for data that is now stale for over 30 days, and with no ability to refresh the data of your old guilds (you’ve left them), does Blizzard expect that to be deleted and thus WoWProgress to lose that data?
If so, is it Blizzard’s intention there can never be a legal means to provide a full guild history on any website?
A practical example:
Let’s say you’ve got:
Cooldude is in Method and you do an api query to detect this.
…Some time later he changes guild…
Cooldude is in Limit and you do an api query to detect this.
… 30 days pass …
Can you list that Cooldude used to be in Method? The api data that gave you that information is now stale for 30 days+ even if Cooldude is still allowing his data to be queried.
