Pray tell, what do you consider to be a WP:RS??? 

You removed an article (Luiza Savage) from the former Category: Harvard alumni and Category: Yale alumni due to lack of reliable sources, despite the fact that I ref'd the most widely circulated news magazine in Canada.  Being a socialist means I don't put much faith in old-guard media, but I'd have thought the Canadian equivalent of Newsweek would suffice for Wikipedia purposes!  All of this is moot now though, as your edit is now buried beneath several others, thus precluding a simple reversion.

Incorrect edits and deletions by bots will tend to discourage new, inexperienced and/or otherwise less-engaged Wikipedians like myself from contributing.  This being the case, perhaps you would consider a 30 day buffer period before bot-editing articles.  The worst part of this is that the target of your deletion was utterly uncontroversial, and didn't violate WP:BLP in letter or spirit.  Frustrating!

One last thing: The only people on Earth with access to the Harvard alumni list (the lone source that's MORE reliable) are...Harvard alumni!  I don't count myself among their number.  If you do, feel free to provide refs!
