Why is my son not an enormous wart?, whilst less precise and academic than:
Why don't warts caused by HPV spread to the whole body?
Why does a wart not spread laterally?
I don't think it's uninformative or misleading. It's certainly unprofessional, but I'm not a professional in this area, and I don't believe this question will be searched for by professionals (although all the professionals I've asked haven't given an acceptable answer as yet). It could be argued that the "spread to the whole body" is clearer for non-native English speakers.
I was trying to attract eyeballs with a click-bait question title. Is a certain level of sobriety required in question titles? Is there an unspoken rule of decorum that was violated?
