Something was removed in early June 2006. Anyone have a full history
dump from before then? I think I have one somewhere, gotta find it
though.
That's just regular deleting, not oversight. There don't appear to be
any deleted revisions, however (Special:Undelete shows no revision
history). It looks like Musical Linguist deleted the article and
restored all but one revision (or possibly a handful) to remove
personal information (I'm guess that's what PI stands for), and then
the next day Jayjg restored that revision(s) too (I guess he disagreed
about it being personal). If I get bored, I might take a look at their
talk pages for those 2 days and see what happened.
