Two things are very interesting here.
1. The amount of words put in my mouth by several people. For example, I've not said that the person is a newcomer or that the site can force anyone to contribute in any way. Rather I'm pointing out that moderators have a history of expressing that such an edit is not contributing at all. And what's a wrongdoing if not a non-contributing edit?
2. The difference in reaction from time to time regarding the exact same thing.

Here a person was notified for doing what I reported above:
viewtopic.php?p=2561890#p2561890

And it was done after I reminded people about the unanimous moderator view in the same thread I linked to above:
viewtopic.php?p=2561742#p2561742

Purely from a policy-perspective, inconsistency is highly problematic.
Going by what some have said above, are we encouraged to report this wrongdoing only if it's by a person who's new to the site? Or also veterans but who do no other update while doing that type of edit? Then what about newcomers who do that edit while doing other edits? Or is it a wrongdoing no matter who do it and in what circumstance?

This is about saving the time and effort of both people doing those edits and people reporting it here.

The site hardly need more vagueness in its policies to be honest. And since I've never see a notification like "hey [user], don't bother editing track lengths to change a few seconds, as different players will display different lengths for one and the same version of a release and others will just edit them back due to their players showing slightly different lengths" as something serious, I really don't see why this need to have several posts this time despite the history of mods telling people not to bother doing those type of edits.

Sometimes this place is like a tombola regarding the different reactions essentially the same post will get from one time to another. That's problematic for any project with policies.

EDIT:
A completely different thing I stumbled upon when linking.


Is Prog Archives in the same category as Last.fm, Wikipedia, and such? From my experience, Prog Archives have tons of info like extensive bio, detailed discography with tons of ratings and reviews, links to forum discussions about the band in question, links to Amazon products of the band, streaming of music, tour updates... And I believe I've added a couple of such links myself. Example: http://progarchives.com/artist.asp?id=378

By "category" I mean that it's most often useless, not category as "unofficial", since it's clearly belong in the unofficial section if belonging here at all.
