Ask HN: How do you handle application spam via Who's Hiring?

I'm asking specifically for people who post in the Hacker News "Who's Hiring" thread. But anyone who is a hiring manager dealing with this problem, I'm very curious about your answer as well.

I'm sure most of you have seen, as I have, spam applications skyrocket over the last few years with aid of LLMs.

High-intent people applying to your company should be a great pool and incredible signal. But the low signal-to-noise ratio, given the amount of spam, makes the juice almost not worth the squeeze.

Do you have any mechanisms in place to handle this? If so, what are they?
