Perhaps the reason scams are reported less by them is that they dont know about scam reports, perhaps there should be somthing ingame to give them direction to the scam report board - however I dont know how it would be possible to stop that from being intrusive

Although a better duel system would be better, it seems very unlikely to be inplemented to me, whereas this seems realistic to implement - you have more knowledge of this than me of course, but thats how I see it
