PieFed blocks !enoughmuskspam@lemmy.world (and a few other communities) by default. At the time of writing this post, you can search for the comm on many PieFed instances and you will not find it.
The block is only by default. The admin can choose to override it. Many big instances have done so, including
- piefed.social
- piefed.world
- piefed.zip
See more information here.
But you showed a constant with the words. Even if you can disable this, I'd call it a "hardcoded list".
