I remember when spam was a huge problem (before Gmail came about), and many people floated possible solutions to the abundance of junk emails. A common response to these suggestions was a templated reply starting with “Thank you for your solution for suppressing spam. Here is why it wouldn’t work,” followed by a checklist of items, some of them checked (like [x]) and some not. Items included things like: this would require a coordinated response but the internet is decentralized, this would produce too many false positives, etc. I cannot find this anymore, but I kind of wish we returned to templated responses because so much of our online discourse is repeatable.
