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.
