I asked admin of my instance few minutes ago and didn’t get reply yet, but it seems your instance(mastodon.sdf.org) blocks pone.social.

EDIT: my instance isn’t blocking mastodon.sdf.org

    SDF has federation issues due to them being forced to upgrade to 0.19 while the stable release is 0.18.5

    They block absolutely nothing, its just technical issues.

      Lemmy and Mastodon are separate SDF services. OP’s instance is blocked for “anti-lgbtq, racism”.
