I beg to differ. The DMARC implications are very different for messages from @linkedin.com or from @tnpi.net. What differs is how some receivers choose to react to those implications. As lists go, for the DMARC implementer and/or tester, this list is a rich testing environment. There's a diversity of implementations and policies among the recipients, the list itself is a "worst case" in that it invalidates DKIM and does nothing to assist with SPF alignment. In that sense, the impact here of DMARC testing *is* disproportionally large. Even so, that large is still not very big.
