Dave, 
You are not alone, yet another crying wolf here... 
I have had some direct correspondence on this very topic. I proposed to change the rule to "Only one signal on the band of operation is permitted at any time". My idea was not accepted. 
Now that you describe a factual occurrence of several signals per band, perhaps (and hopefully) the contest sponsors will revert to considering this topic again.

Although it is certainly implied, the rules listed on the WW-Digi 
website do not specifically prohibit using more than one signal at the 
same time ON THE SAME BAND for the single op category.  They say that 
transmission can only be on one band at a time, but they don't say you 
can't make multiple transmissions at the same time on the same band.

The reason I bring this up is that I just witnessed 5T5PA making three 
separate FT8 transmissions on 20m to three different stations all within 
the same fifteen second window.  A short time later I saw two separate 
transmissions from him to two different stations (and different stations 
than the previous three), again all within the same fifteen second 
window.  Each simultaneous transmission was spaced exactly 60 Hz apart, 
and the software cleanly decoded all signals as if they were from 
different callsigns.  5T5PA expertly managed all the QSOs cleanly.

Interestingly enough, even though I've worked 5T5PA before, JTAlert only 
labeled one of the three as a dupe.

I can think of more than a couple of ways 5T5PA could be doing this, and 
for casual operation I see no problem with it.  For a DXpedition, it 
might even make a lot of sense.  I don't remember it being against 
FCC/other laws, but I could be wrong about that.  In any case, it seems 
to me that it could open up the possibility for some controversy in a 
contest.

Or maybe I'm just crying wolf here ...

Dave   AB7E
