Unregistered (operative word #1) users with only one post (operative word #2) that got deleted by Community (operative word #3) after spam or offensive flags should be deleted/destroyed automatically.
These posts are typically made by:
- hit and run trolls
- who'll never come back, and
- just waste bytes in our database.
While bytes are a dime a million, unregistered users are worth even less than that. In the worst case scenario of a legitimate user getting this treatment will simply have to fill in their details again.
This is even more important now that the SmokeDetector project casts automatic flags on certain spam posts halfway to deletion, and there exists a proposal to change it from three to five autoflags. This means that a lower and lower proportion of accounts that exclusively post spam get destroyed. It's important that the accounts get destroyed too.
