I think there is also the molars and general jaw shape to consider. Carnivores are not just identified by their fangs, they have generally a different structure and layout of their jaws that is made to lock into a prey animal or tear out pieces of flesh.
In contrast, many herbivores have teeth laid out to grind down plant matter (think cows or goats) and their mouths are laid out to chew off vegetation with very articulated lips to assist. Even if these camels have pointy fangs, the rest of their mouth would indicate they eat primarily plants.
I just yesterday saw a post how disabling downvotes for an instance that still acts as part of the greater fediverse causes issues and unfair advantages with posts being created there that can achieve a high score very easily, even on accident.
I would expect Lemmy to rework that function to avoid these issues so that up- and downvotes are either mandatory or can only be disabled together. I would not recommend trying to find an instance based on if they practice this most likely not here to stay functionality.
