== The deletion/move/undeletion thingy == 

 Hi, what I did was remove a few revisions from the page history because they contained personal information and libel, and those things should not be online for all the world to see. Most vandalism is "harmless", we simply revert and let the vandal revisions stay in the history, but when someone named is falsely accused of dealing with cocaine, or personal phone numbers with name and address are given, those revisions need to be taken off line. There are basically two ways of doing this for administrators without oversight access (oversight access is rare, most who have them are current or former arbitrators). 
 *The simple way is to simply delete the article, and then restore all the non-offending versions. The problem with this approach is that the next time someone adds personal stuff into an article which needs to be deleted, chances are the next admin who deletes revisions will overlook that there are previously deleted revisions with libel, and may wind up restoring those by accident. 
 *What you saw me doing was the complicated approach. It consisted of first deleting the article, then restoring the "offensive" versions so that I can move them out of the way (in this case to a subpage labelled "/dump"), and then delete them again. Then I can go back and restore the article without the offensive revisions remaining in the page history (the final step is reverting away the a vestigial redirect from the move, that is the edit with "restore content"). It is a laborious process, and it is rare that I do it. In this case I considered the issue serious enough that I blocked the IP which added the libel for a week and e-mailed the school to report it. 
 Yours,
