Single post in Implementing A 'Block' Feature

sorry to jump in again i think editing it into my previous post would make it go under so: got a concern for the spam filter how are dncs supposed to work alongside it? lets say someone has me blocked they dont wish to see me but they unhide my trade posts or my auctions to partake occasionally because they dont mind interacting with me that way, i send a dnc, it gets filtered into the spam folder, they come into my trade shop/auction/etc. what now? they unknowingly broke the rules by doing so
