It has the exact same metadata as the fabric example mod and it looks odd.

From the FMJ:
"description": "This is an example description! Tell everyone what your mod is about!",
"authors": [
"Me!"
],
"contact": {
"homepage": "https://fabricmc.net/",
"sources": "https://github.com/FabricMC/fabric-example-mod"
},
"license": "CC0-1.0",
"suggests": {
"another-mod": "*"
}
It's also not marked as a library in modrinth, so it's not hidden either.
