Strange removal of a decent answer

Question

The only answer provided to this question (also automatically removed, so now it is accessible to 2K users only) was "hammered" by a moderator.

However, the question had and has a good score and there are no comments to justify its tragic end. Its edit history indicates complete removal and then a restore.

It is true that the question is rather poor, but the answer looked fine. Removal of the answer most probably led to automatic removal of the question ("dead" - low score, old and no answers).

Note: I am not sure if it matters, but both users (question author and answer author) are currently suspended.

Question: Why was the answer removed?

Answer 1

This seems to be a co-incidence of several events in a row:

1. There was a content dispute about one of the user's answers (see this Meta post)
2. Instead of editing their answers, as the community suggested, the user got furious and started vandalizing their own posts across the site — see 1, 2, 3, 4, 5
3. For some posts, other users rolled back the recent edits
4. For other posts, other users decided to remove the vandalized posts altogether (which, I admit, might be a better choice than the rollback)
5. After deletion of its single answer, the question "Gun violence" became orphan (negative score, no answers) and subsequently deleted by the SE maintenance script
6. Note: the answer has rollback edit after it has been deleted, so this couldn't prevent the maintenance script to delete it.
