[Nomes77]

A solution to ban invalid issue.

1. Install https://github.com/riyadhalnur/issuelabeler
2. Put the following in .github/labeler.yml

excludeLabels:
  - ongoing 
custom:
  - location: title
    keywords:
      - 'youtube'
      - 'facebook'
      - 'twitch'
    labels:
      - duplicate

3. Make .github/workflows/label-commenter.yml and put the following in it:

name: Label Commenter

on:
  issues:
    types:
      - labeled

permissions:
  contents: read
  issues: write

jobs:
  comment:
    runs-on: ubuntu-20.04
    steps:
      - uses: actions/checkout@v2
        with:
          ref: master # Set your default branch

      - name: Label Commenter
        uses: peaceiris/actions-label-commenter@v1.10.0

4. Put the following in .github/label-commenter-config.yml:

labels:
  - name: duplicate
    labeled:
      issue:
        body:  |
            @{{ issue.user.login }}, please follow the issue template.
            > This is NOT a [YouTube](https://www.github.com/uBlockOrigin/uAssets/issues/19976), [Facebook](https://www.github.com/uBlockOrigin/uAssets/issues/3367) or [Twitch](https://www.github.com/uBlockOrigin/uAssets/issues/5184) report.

Giving it a try: 791500c

Still need to see if it will work as expected.

Based on #21625 / #21624 actions works too slow/rare at day.

The code

excludeLabels:
  - pinned
custom:
  - location: title
    keywords:
      - 'youtube'
      - 'facebook'
      - 'twitch'
    labels:
      - duplicate

may close the ALL twich.tv / facebook.com issues as they are not pinned.

[Nomes77]

not true.
It only works when opening a new issue or when changing the title of an issue.

[JohnyP36]

@Nomes77 Why then exclude labels pinned?

[Nomes77]

The title of the pinned YouTube has changed multiple times in the past. Giving those issue the label pinned or ongoing wil prevent them from closing.
