title: Toxicity Analysis in YouTube Live Chat

A little analysis and experiment on a flock of toxic people.

# Why

|
||||
The motivation is quite simple; I just feel sad when they sound suffered from toxic chats. The goal is also simple: design an automated system to spot toxic chat and quarantine them.

I need a myriad of live chat comments and moderation events for this.

Unfortunately, YouTube API does not offer a way to retrieve these kinds of events in real time. Which is so crucial because live streams are only place we can observe moderators' activities through API response. Once it gets archived, these events are no longer available.

## Collecting Crusts

So, I ended up developing a library to accumulate events from a YouTube live stream, plus a fancy CLI app mimics live chat. It accepts YouTube video id and save live chats in [JSON Lines](https://jsonlines.org/) format:

## Make a Bread Rise

A line with white text is a normal chat, red text is a ban event, and yellow text is a deletion event.
|

I know, that's not scalable at all. A new live stream comes in, I copy and paste video id into the terminal and run the script. How sophisticated.

Thankfully, there's a great web service around Hololive community: [Holotools](https://hololive.jetri.co). They operate an API that gives us an index of past, ongoing, and upcoming live streams from Hololive talents.
|
||||
|
||||
Here I divided my system into two components: Scheduler and workers. Scheduler periodically checks for newly scheduled live streams through Holotools API and create a job to be handled by workers. Workers are responsible for handling jobs and spawning a process to collect live chat events.

I run the cluster for a while and by far it hoards approximately 1 million comments per day. Now I could reliably run my own bakery.

Okay now there are five million chats sitting on MongoDB store. Let's take a close look at these before actually starting to build a model.

Glancing at `.afphoto` and `.afdesign` in Finder, I noticed that it has a QuickLook support and an ability to show the thumbnail image. So these files should have thumbnail image somewhere inside its binary.
