slack-moderator

slack-moderator

slack-moderator provides the same message reporting functionality as slack-report-message, but overrides the behaviour for Slack Admins and Slack Owners to instead function as a user and content removal tool:

This vastly improves the experience of removing troll users who have been spamming undesirable content. The user themselves will be deactivated (without going through the Slack user deactivation mess) and all their content from some time span will be removed.

Note: slack-moderator uses an undocumented API to deactivate users. This API is also only available on paid Slack teams. Content removal uses documented APIs and should work on all Slack teams.

Configuration

slack-moderator requires a configuration file, by default called config.json in the working directory. It must look like this:

{
  "signingSecret": "some_slack_signing_secret",
  "accessToken": "xoxp-some-slack-access-token-these-are-very-long-and-start-with-xoxp",
  "adminToken": "xoxp-another-slack-access-token-that-also-starts-with-xoxp",
  "webhook": "https://hooks.slack.com/services/Tsomething/Banotherthing/somerandomsecret"
}

signingSecret, accessToken, and webhook are all values provided by Slack when creating and installing the app. Check out the slack app creation guide for more details. Because slack-moderator uses an undocumented API it also needs a legacy token, which is provided as adminToken. A legacy token can be found on Slack's Legacy Token page, under "Legacy token generator".

Slack setup

The slack-moderator app must be created by a user with Admin or Owner powers. It requires the following OAuth scopes:

• chat:write:user
• incoming-webhook
• files:write:user
• commands
• search:read
• users:read

slack-moderator also requires the following interactive components:

• Callback ID: report_message. Recommended action name: "Report message"

slack-moderator does not require any event subscriptions.

The slack app creation guide explains what to do with these values.

Deployment

Kubernetes runs slack-moderator in a Kubernetes cluster; check out the config.

slack-moderator can also run on Google App Engine. To do this, create a config.json file in this directory as described above and then run gcloud app deploy, using a Google Cloud Platform project that has App Engine enabled. For most Slack teams, slack-moderator should fit in the free quota.
