But YouTube especially seems caught off guard with not having thought through a problem like this. Sundar Pichai (CEO of Google) called it a "hard computer science problem". Ironically, John Fish, a Harvard undergraduate with a video channel on undergraduate life with a tech major (computer science), while usually non-political, has dropped hints on his channel that these kinds of problems are coming for the whole industry. It's as if Ford had created a "final exam" problem for a university journalism course.
There are important stories today on Twitter, too, about embedding other people's tweets in direct messages, and about little known ways to troll with empty honeypot accounts; Twitter will address these but I did not get around to reporting about them as issues in detail today.
