On a more serious note: Given that many user communities in the FediVerse are people conscious of their privacy and of suffering pile-ons by large majorities of outsiders, I wonder how many more examples of this there will be before people start asking the developers for out-of-the-box defaults that simply blacklist all requests that come in with referrer headers containing news.ycombinator.com and other similar "Slashdotting" sites.
