Chances are it hasn't been federated by the instance yet. You can force it by using the search feature and searching @magazine@instance
So if you search @[email protected]
it should federate. It won't load old posts but anything new should show up.
Edit: this usually will work, but not in this case. I checked out the website itself and sorting by all communities rather than local only shows local posts, so maybe they completely disabled federation
Should be using AdNauseam by default imo. Based on uBlock but also clicks on every ad to cost advertisers money for wasted clicks.
