Failed SPF/DKIM/DMARC doesn't trigger abuse reports through feedback loops. Marking messages as spam does. These are cases where one party has decided to mark one or more emails as spam. None of the emails in question are bulk messages -- it's all sent from properly authenticated domains and most of the mails are from ongoing conversations. A lot of it's correspondence between private individuals, others between businesses. Giving people a Junk button is a bad idea at scale. There's been a lot of discussion about this being a linguistical issue (that people don't realise Trash and Junk are different things), but I regularly see people marking entire conversations as Junk when they're angry about not getting an invoice's due date moved, or when arguing with a family member. The worst part is that people don't realise the Junk button often triggers a report to the sender's ESP. The contents of the reported emails are usually included, and in most cases the reports are read by someone else. All this is also processed by spam filters, regardless if it's simple SpamAssassin/Bayes setups, or more advanced systems at Hotmail/Gmail.
