Allow user to remove postorius account and associated mailman core user data
It is possible that users may want to remove all data stored by a Mailman install (e.g. due to privacy concerns). Things they might want to have removed include:
- The django user account used by postorius and hyperkitty
- Any subscription information stored in Mailman core (e.g. unsubscribe from all lists, remove any nonmember rules that would indicate their previous activity here)
- Any posts in the archives they have sent.
The first two are much easier than the 3rd, and it's worth noting here that traditionally archives have been non-editable so providing this ability would break assumptions about mailman archives that we might not want to break. I would suggest that anyone fixing this bug should concentrate only on the first two items until this is debated on the mailman-developers list.
This issue is based on #46 (closed), which was lacking in information.
