It really makes you consider. “I want to do this job or this job is the most realistic one for me to get” instead of just buying tons of lotto tickets to get a google interview
This is ultimately the common factor in spam mitigation. If the costs of transmitting or submitting a message are nil, then the spammer will submit them.
It's also why reducing costs of communications can backfire in all kinds of obnoxious ways. I remember getting my first email account, nearly forty years ago now, and being able to communicate near instantaneously, and with no cost, to ... a very, very, very small handful of people.
Even in the corporate world of the early 1990s, email addresses were sufficiently rarified that for the most part you'd communicate with a few colleagues at the same firm, and perhaps some contacts at other companies, if you were in a technical position (as I was at the time).
I can distinctly recall being in a bookstore in the late 1990s the first time I heard a mother talking with her daughter about a new friend the daughter had made, and the mother asking if the daughter had shared her email address.
Other than cost imposition, the best suggestion I've had for information overload is to have a cheap, unbiased, low-cost, no-regrets information rejection capability.
