Balance/hide/ignore/delete
From eg
This is a wiki best practice of living ontology fully documented for political wiki purposes at openpolitics.ca.
Rather than risk accusations of sysop vandalism, when dealing with content problems, it's better to call for explicit efforts to balance content and then slowly restrict page visibility. After some reasonable interval and calls to concerned factions to balance the page with new pages or edits, proceed to verb:hide, verb:ignore and verb:delete pages containing unbalanced claims. This protocol is the most fundamental operational archive maintenance protocol in living ontology.
The alternative is to lock pages a lot and fight over who has infrastructure owners trust, and watch everyone degrade into sysop vandalism.
[edit] never delete?
There are strong arguments to never delete anything, for accountability. However, there are circumstances such as court orders, malware, copyvios, liars exploiting troll-friendly practices, misleading tyops that pollute namespace, and extreme balance problems that may all legitimately lead to deletion. As long as at least one archived version contains the controversial content, and the deletion was not out of order, deletions can remain with the rules of open politics in force. Debate this issue further at talk:balance/hide/ignore/delete or the parallel page at openpolitics.ca.
These arguments to never delete are also extremely strong arguments to follow a rigorous organization protocol such as balance/hide/ignore... first. If deletions are inherently undesirable, then all measures should be taken to relieve the pressurs that lead to them.
