I call this the "we don't do anything special" fallacy. They consider hackers to be something like in the movies where a team of slick black leather clad folks plan a digital heist, and why should a bunch of movie stars care about our little business.

In truth it's much much more like how Google just has computers trying to index every site on the internet that they can find. Most of the attacks these days are broad searching things, just testing every exploit they can against every site they can.

Also, seriously, Google will find and index those GET+DELETE non idempotent URLs and ruin their day.
