I have a Flickr account with several thousand curated photos in it. Several years ago I let myself get convinced into turning on automatic photo upload. Before I knew it, my photostream was filled with garbage screenshots and photos of people blinking. It created 100s of tiny albums that cluttered my page and made my Flickr page a mess that I could no longer use, and I mostly abandoned photography.

I spent several days this year deleting all of those photos (because of course there was no batch delete that I could find).

Hopefully Smugmug does something great!
