According to Rimu Atkinson, the main developer of PieFed, all PieFed instances come with a 3000-long block list of resources that cannot be linked to. These include all sorts of right-wing outlets. There is no easy opt-out, forcing existing instances to follow the blocklist.
The flagship PieFed instance also rolled out a feature marking various other sorts of outlets - among them, resources considered AI slop and Marxist outlets. These are specific to piefed.social.

Why YSK: Many users have hard time choosing between Lemmy, PieFed, and Kbin/Mbin. Users that prefer a more curated and politically uniform experience might prefer PieFed over the alternatives. Users that are right-wing, Marxist, or generally concerned about global censorship of the Fedi-/Threadiverse, might opt for other options instead.
Note: The post is only meant to inform users of the potentially important differences between Threadiverse platforms. Any ideologically charged discussions are better left in the respective topic.
Only mildly. At least on Lemmy, I haven’t used piefed. The import/export went really well when lemm.ee shut down. And luckily there was an instance with a similar stance (lemmy.zip) to letting you decide what you want blocked.
