Hi all,
When I was MS lead, I kinda schemed and drafted a plan to implement some form of duelling system to actually mitigate the risks of being scammed. Essentially, I wanted to make any system that an ordinary user engages in, self-sufficient to a point where the user doesn't really need to worry or waste their time because an angry Timmy got 3-0d. The main issue with this at the time was the lack of developer time - which is obviously understandable. But I apologise for not delivering, but I do think it is a good idea, and the concerns around it are really trivial attempts to be against change - which could be remedied with simple answers.
Again, apologies for not delivering on that, however, I am always open to sharing my plans with those if they choose to pursue it.
