The OP linked to the function with the 'enoughmuskspam' filter in it: it's here (line 352 if it doesn't auto-scroll down).

As mentioned, it's a bulk-community import function, that new admins can optionally use to kick-start a new instance.

The code you've linked to is another convenience function, for users this time, that will optionally add the relevant values to their content filters for the 'All' feed. It's also not a federation block, and it's common enough for fediverse users to want to hide posts about those people that it's value arguably overrides any perceived messiness about 'hard-coding' their names.

Anyone who takes the time to understand PieFed's codebase could find plenty of things to legitimately criticise. To my mind, though, it seems against the social contract around open-sourcing one's hobbyist project, only for people to then be snarky about it online. If there's bits of code that look like they were written on someone's lunch break, that's because they were.

The frustrating thing about this post, and the (now deleted) post before it, is that someone has taken more time to create some shit meme than they have reading the code they're haphazardly attacking. I've no idea why PieFed has suddenly come under some Lemmy users sights, especially since the whole point of federated social media is that it shouldn't matter what client someone uses, and how much it reeks of "People Front of Judea" bullshit.
