Can YouTube stop putting ads next to ISIS videos?

YouTube are suffering some problems currently. Ads from big corporate advertisers are appearing next to content from ISIS and other extremist groups.

YouTube and the other internet giants point out that 400 hours of video are uploaded to YouTube every minute. So that it’s almost impossible to find bad content.

However this may be the wrong way to look at it.

There are really two ways to fix a problem like this.

Option 1: Whitelist appropriate YouTube channels

The first way is to whitelist YouTube channels that advertising appears against. For instance you get the most popular 100,000 YouTube channels and put them through a verification process that weeds out inappropriate content. Human tagging, combined with machine learning (in the literal sense), would make this expensive but not impossible.

The problem for YouTube is that they’d then have to remove, or change, advertising against all other channels. Back in 2015 there were 837,000 ad supported YouTube channels. It would be reasonable to assume that there are at least twice as many channels today.

However the, say, 1.9m channels which would not get verified are 95% of the channels, but likely only, say, 20% of the views. So YouTube would need to give up that ad inventory. Or it could sell it to less squeamish advertisers at a lower rate.

Option 2: Find inappropriate YouTube videos

The second option is messier but less costly for YouTube. It relies on the fact that people who put up ISIS videos want them to be seen. So YouTube can put human review in for any video that:

  • Isn’t from a known safe channel or user.
  • Has any tag or keyword that is risky (e.g. ‘Iraq’).
  • Has more than, say, 400 views (And so is likely to have any meaningful impact)
  • Is gaining views quickly.

Add these together and the number of videos to review drops dramatically. Get your reviewing mechanism to learn from human judgement, and you should, fairly quickly, be able to handle the problem.

YouTube/Google have some of the world’s best machine learning experts, huge budgets and good reasons to move quickly. They can fix this.
