[Self-plug] After building poachme.dev with a friend, I have personally found that a lot of people who spam really do it because it's low cost and wasting your time costs them nothing so I personally grab the standard reply message template and hit them with a

"Great. Please book a slot on my calendar and we can chat more about this: https://bk.poachme.dev/Lazaro"

I know they didn't "read my profile" or "find me to be the best candidate" so I just respond in kind... you wanna waste my time? Fine, I'll sit through your shpeill for $100 and if I'm so important to you, you'll pay it, if not, well, that's fine too.
