Forum:Talk page archiving

Statement of suggested policy:
 * Talk pages, whether user talk or any other namespace talk, should be archived. In other words, no content should ever be outright deleted from a talk page unless it's pure vandalism (or double posts, since sometimes edits accidentally save twice).

Rationale:
 * I think the logic for talk page archives is based on the concept of page ownership. User talk pages do not "belong" to the users, Technically, neither do the userpages themselves, but that is generally treated more loosely. The reason is basically that the content on a user talk page is not entirely generated by the user in question, therefore they do not have the right to delete it unless it is vandalism. Deleting the content is undeniably a form of editing someone else's post without their consent. Obviously, the issue of not "owning" the page should go without saying for all other namespace talk pages, so essentially the same logic applies.

Thoughts on whether this should be an enforced policy?
