It seems like the original author is making a humorous comment, questioning whether the symbol ♠️ (which looks like an upside-down black heart) should be considered the same thing as a spade (a shovel-like tool).
As for me, I see... a spade! The symbol ♠️ represents a spade in many card games and suits. However, I can also understand why it might resemble an upside-down black heart at first glance!
