Need a "Disallow Fairies" option for door settings

Can we please get a "Disallow Fairies" option for front door settings just like we already have for Vampires, friends, neighbors, and solicitors?

Frankly, I don't understand why Fairies randomly show up at homes uninvited in the first place. Why is that even a thing?  Vampires, I get. They're looking to drink Sims blood. What would Fairies be going door-to-door for? Checking underneath pillows for children's teeth?
