From the previous[1] statement:
The unauthorized party also accessed a “small number” of images of government IDs from “users who had appealed an age determination.”
It makes sense they have to hang on to the ID in case of processing an appeal, which probably doesn't have the highest priority and hence stretches out in time.

The funny thing about this is that it kinda makes it OK for Discord to still have the records. But...
1. Discord still got hacked despite being a company that must have passed some level of authorised audit in order to be able to store government ID cards. (who audits the auditors? Is there an independent rating of security audit companies? What was the vulnerability? Was there any Government due diligence?)
2. This is a great example of why "something else" is needed for proof of identity transactions over the wire, and this "something else" should exist, and have existed for long enough to develop a level of trust, before Governments start mandating that private companies audited by other private companies must undertake actions that require the storage of Government ID documents. Banking level security and regulation should be required for any aggregator of such sensitive data. That fucking Discord had Government ID docs at all is beyond ridiculous. More-so for Governments of countries other than where Discord was incorporated. A state-sponsored Russian / Chinese / North Korean / Iranian / <other> Discord-alternative would have been an interesting situation. The implicit trust in Discord, and any other "app publisher" requiring ID confirmation is just peculiar.
