I'm talkink about stored IP addresses, not email addresses at this point.
According to the Member History
******** was last used at 04/17/2023
******* was last used at 04/17/2023
******** was last used at 06/05/2022
So it's stored longer than 30 days. Or do i misinterpret something ?
This user has e.g. a even longer "history": Member History
Besides that, it would be interesting how to delete certain PII data after 30 days like the IP addresses.
