That's an interesting frequency to select for the source of voice qrm. I
wouldn't be so fast to blame VE's or other non-US stations for this increased
interference. That is the BFO (14070 dial) frequency for virtually every
transceiver running PSK on 20 meters.
With the proliferation of PSK31 using soundcard technology, my first
inclination would be some operators do not mute or disable their microphone
when using AFSK for these modes.
So now there's a live mic in the shack while they are happily PSKing away.
Everything is fine until they shout... HEY MARTHA, WHAT'S FOR DINNER TODAY?
Instant qrm. 50 years ago the operator knew when his microphone was live and on
the air! :-)

I have been hearing more activity that appears to be illegal voice than
I have ever heard in the past 50 years. It is so bad that a number of
times I have been hearing voice transmissions that interfere with WWV
reception!
Probably much of the voice activity on the ham bands that are in the
U.S. text data portions of the bands are due to operators in other
countries moving lower. I know that Canadians in particular were very
upset with the liberalization of the U.S. voice frequencies some years
ago and declared that they would move down below the U.S. frequencies.
In fact, I remember someone commenting that if the U.S. ever increased
liberalization of the voice bands, they would just move down even
further. Since the more recent increase in voice bandwidths for U.S.
hams this may have caused at least some of this.
Although on 40 meters you will often hear wide split operation because
those outside of Region 2 may not have as wide a band, I recently heard
a CU2 working narrow split down around the digital area. When the 10
meter band is open we can have many pirates operating in the text data
areas of the band since that likely seems like an unused part of the
spectrum to those stations.

We hear a lot of that throughout 40, 30 and 20m and everywhere in
between. All Asian pirates, fishing vessels, phone patches, all sorts
of things. It can really ruin 10132 for a start.
