For one thing, you can configure a DMARC policy without a reporting address. For another thing, you can use third-party services, such as https://dmarc.postmarkapp.com/, to aggregate DMARC reports for you (if you're fine with the privacy implications of that).

You can also just set up DMARC without a reporting endpoint. But DMARC aggregate reports are very useful, so I wouldn't recommend using DMARC without reporting. Also, you do not receive a report 'every time someone spoofs you', but rather periodically, at an interval which you can even configure.

That said, DMARC aggregate reports are not supposed to be human readable. You don't want to set the reporting endpoint to your personal inbox. You need a DMARC aggregation tool, such as included in https://www.mailhardener.com to process them. (full disclosure: I work there)

I have some procmail rules set up that sends most of that stuff to a different mailbox that I never look at.
