Unlike the official WSJTX software, some third party variations will
log a QSO every time it sends an acknowledgement (RR73) for a report.
If the calling ("hound") station does not hear the acknowledgement
and sends his report again, the third party software is too "dumb"
and treats the repeated report as another QSO. When this happens
the DXPedition can rack up multiple QSOs - generally one minute apart.
This is a problem of sloppy programming on a noisy band ... not DXers
who are intentionally making multiple QSOs.
Like it or not, FT8 has been a boon to many DXers with limited antenna
situations and noisy locations.

It is unreasonable to assume that all FT8 QSOs are with robots. I know
some of the very experienced CW ops who run FT8 on expeditions. WSJT-X
software makes the mode quite time-efficient for expeditions. It's a
replacement for RTTY, not CW.
It should be observed that no less a great engineer and operator than
AA7JV is a strong believer in the mode. George is one of the best
operators and most innovative engineers I know. And he's got great big
balls! Check out his history. This is a guy who would swim hundred of
yards to to his boat anchored offshore to upload the log, which was on a
thumb drive in a baggie in his mouth. And who designed very effective
topband antennas specifically for the conditions on the islands where he
planned to set up. And who designed and built diplexers for Topband
transmitting antennas so that both CW and FT8 stations could be active
simultaneously every night, so that the "magic" openings that usually
occur one or two nights out of 3 weeks would not be missed. And who
invented "Radio In A Box," drastically reducing the cost and physical
difficulty of expeditions to islands.
I made several QSOs with the CB0 team this weekend during ARRL DX CW.
Great ops made it easy to work them. I did not work 160 this weekend --
storms have taken out all of my RX antennas.
