The mistake they made was allowing visitors to trigger the generation of articles via visiting any arbitrary URL.

A more resilient concept would have been, have a few "seed" articles in place, and then only allow for the creation of new articles by clicking a link in an existing article.

Just in the comments, right? That is where I see it. If I were the site owner I would just turn comments off. It was a cute idea when someone on HN suggested it, but without moderation open commenting becomes a cesspool in a hurry.

This is why we can't have nice things.

Looks like someone scripted `curl` in a loop and generated thousands of permutations of hate content.
