Synapse User Auto Eraser

This is a simple script that will erase users, their media, and redact all their events from a Synapse server based on specific criteria:

• not an admin
• not a guest
• not deactivated
• not contain a specific string in their MXID
• not older than a specific threshold in days

It was developed for the etke.cc demo server for the purpose of cleaning up the user database.

Another purpose of this repo is to be a test stand for migrating our gitlab repos to github

Don't expect this to be a full-featured tool, it's just a simple script that does one thing.

Configuration

Configuration is done via environment variables (.env file is supported as well). The following variables are supported:

• SUAE_HOST - Synapse server host, e.g. https://matrix.example.com (without trailing slash)
• SUAE_TOKEN - Synapse homeserver admin token
• SUAE_PREFIXES - Space-separated list of additional MXID prefixes that should be excluded from deletion
• SUAE_TTL - Maximum age of the user in days, users younger than this value will not be deleted
• SUAE_DRYRUN - If set to true, the script will only print the list of users that would be deleted. You WANT to run it in dry-run mode first to make sure you're not deleting the wrong users.

Check .env.example for an example configuration.
