I would suggest that opponents cannot be paired with the same opponent more than (X) number of times in a row. Whether that number is 2,4, 8 whatever.
It seems that some competitors login to see who is available to play, and if its (for instance) draw-master Arasanx(C) they just leave.
It seems people can get caught in a cycle of back to back pairings that just wont stop because of timing. I’m not certain that this is in the spirit of the broad based competition in such a tourney.
