Product Design: Consider partial thread deletion for deleted accounts

[coderabbitai]

Background

When users delete their accounts, we currently delete all their threads after the 30-day grace period.

Proposed Enhancement

Consider a more nuanced approach where:

• Private threads are deleted completely
• Public threads remain accessible but with user attribution changed to [deleted] (similar to Reddit's approach)

Rationale

• Public threads may have value to the community even after the user is gone
• Users explicitly consented to make these threads public/indexable
• This preserves knowledge while respecting privacy for private content

Current Implementation

The current implementation in PR #468 deletes all threads regardless of visibility status, which is acceptable for the initial version.
