-- Built-in, automatic support for secure HTTPS with [Let's Encrypt](https://letsencrypt.org/).
-- Strict privacy enforcement for posts and strict blocking logic.
-- Import and export allow lists and deny lists. Subscribe to community-created block lists (think Ad blocker, but for federation!) (feature still in progress).

+- [Import, export](https://docs.gotosocial.org/en/latest/admin/settings/#importexport), and [subscribe](https://docs.gotosocial.org/en/latest/admin/domain_permission_subscriptions) to community-created domain allow and domain block lists.
 - HTTP signature authentication: GoToSocial requires [HTTP Signatures](https://datatracker.ietf.org/doc/html/draft-cavage-http-signatures-12) when sending and receiving messages, to ensure that your messages can't be tampered with and your identity can't be forged.
