I would have put this in the MediaWiki software subforum, but nobody ever reads anything there, so here it shall go.
The basic unit of the MediaWiki platform is the "revision," each of which has several attributes, including a timestamp, an editor, a page, a summary, and all those things we all associate with an individual "edit".
I'm wondering if any of the current or former admins here know whether changes to a revision's attributes are among the tools available to users at any level (other than database admin).
If so, is a record kept?
To illustrate an example, as mentioned here in another thread, Jayjg has made several "oops" IP edits over the years, most of which were later Oversighted away. Some, on the other hand, were later changed to appear to have been made by Jayjg.
Here's a good example.
In the 1/25/2006 and 8/16/2006 database dumps, that revision is attributed to 209.47.33.228 (consistent with the signature). However between 8/17/2006 and the 11/30/2006 dump, the revision's editor attribute is changed to Jayjg, as you see it remains today.
I'm finding quite a few of these changes, by the way, and just as with this example, the article logs reveal nothing.
I guess my questions are: who has permission to do this sort of thing, is it at all common, and is there any transparency/accountability associated with it?
Maybe to put a finer point on it: could a random (non-Jayjg) editor request that unintentional (or intentional fore that matter) IP edits be retroactively altered to reflect his/her having been the editor?
