>I don't understand the security or GDPR references.

Well this is amusing. I wondered if anyone had ever implemented some
version of the http reporting in early DMARC drafts, so I set up a new domain
with a server that will accept POST or PUT requests and added its URI to my
DMARC records.

I didn't get any of those (the POSTs below are not to the right URI)
but it's impressive how fast Russian bots started to probe it, within
hours.

This is not a reason to avoid https reporting. Every web site gets
probed like this and so long as your web server rejects unknown URIs,
they're harmless. After all, my e-mail reporting addresses get a
certain amount of spam, too.

R's,
John
