Actually there are ways that one can be sure once the people are in the center of the arena. One woujld be to have the referee check a time-stamped screenshot of their inventory and equipment. The timestamp would have to be after they had come to the center of the arena out of trading range with any partner.
Well, that would take the fun out of anything. 20 mins checking screenshots, and making sure the people that just entered the arena can't be in 20m range of the others before beeing checked? Yeah, right :-) I'm also pretty sure a dedicated homin would be able to cheat anyway :D
And ofc, there're the guys who just want to ruin it for everybody. After 20 mins checking screenshots, the last one isn't "clean", and that damn player ran to the group of screened players... Well... we'll restart again, no harm done.
:D
