Mastodon domain block exporter script

Export domain blocks from a Mastodon server into an importable CSV file.

To use the script, download and run script.py following the format:

python script.py domain reject_media reject_reports obfuscate

From Mastodon's documentation:

• reject_media: Whether media attachments should be rejected.
• reject_reports: Whether reports from this domain should be rejected.
• obfuscate: Whether to partially censor the domain when shown in public.

An example command to download domain blocks from mastodon.social with reject_media and obfuscate set to false, and reject_reports set to true.

python script.py mastodon.social true false true

Running this command will create a file mastodon.social-domain-blocks.csv which you can then import from the /admin/export_domain_blocks/new page on your server (eg. https://mastodon.social/admin/export_domain_blocks/new).

You will be prompted to confirm each individual domain before it's imported, and you will also be warned about any existing follow relationships that would be severed.

Note that not all Mastodon servers make their domain block lists publicly available. In those cases you will see a 403: Forbidden error.
