Topband: Region One stations below 1810 kHz

[Tree]

All -

A friend of mine alerted me to the fact that he heard a QSO take place
between someone in the USA and Europe below 1810 during the Stew.  I did a
little research and verified that this QSO did take place - around 1805
kHz.  However, the European reported the QSO on 1810 kHz.

During this investigation, I have found more of these QSOs - including
about two dozen with one station who was on 1808.9 kHz (per RBN).

Perhaps the rules have changed recently, and these frequencies are
permitted for Region 1 stations?  I see all sorts of countries in the list
I have generated so far.

And if these are "illegal" contacts - what should be done about them?

And if a Region 1 stations modified his log to change the frequency
information to make it look legit - is that unsportsmanlike behavior?
