I mean, you definitely aren't wrong about the lack of communication.
The only thing that I know of/remember about a date, neither Abbas nor Tim were involved, but that Pfieffer had told Mensa to not raid after a certain date, but that was never told to Vanguard until after we had already countered, and no one else from Mensa had either.
I had logs from Pfieffer saying that according to their raiding rules, Vanguard was free to raid and in an almost antagonistic way, told me that we were free to retaliate. Basically all of our alliance had been beiged (which is when the raiding stopped because we were all beiged), and during that is when Pfieffer went and told Mensa to not raid us without telling us. We were 100% expecting Mensa to continue raiding based on the information we had, which is why we declared on them.
