I unexpectedly found myself in Anthere's position today - checked on my gallery of fair use postage stamp images today, and as expected, images for which I hadn't yet written the article had been deleted, but also some images long used in my article about Austrian stamps. Turns out that some anon had emptied out half the article, this went unnoticed for several weeks (it's on my watchlist, but must not have checked it that day), then while I was on vacation and not examining watchlist daily, the bot came along, marked the images as orphans, and a couple weeks later somebody else deleted. After *that* a nice anon quietly restored the article, leaving it unclear why the images were deleted in the first place.
No moral to the story, except perhaps that figuring all this out (and re-uploading from my backup copies) is time that could have gone into content development. I suspect all this publicity is going to bring a new crop of vandals wanting to "prove" that WP is a failure, so even more time will go into defending rather than improving.
