Okay so I'm gonna speak from my expirience when banditing as I have personaly been doing it almost since the beggining of this map so I'd say I've seen the good and bad of banditing but to start of, if you do not notice my emote when you're all alone running on the roads then either you're running around in F1 which then if I down you without the knowladge of it. To me it would look like you were just making a run for it so it would seem rightful to down you and pop you only if you run again and if you just don't notice it, it's your problem, not mine.
Secondly, it's often hard for a bandit to specify who he wants to halt as by the time you type out a player's RP name or whatever other specification you wish, your target is already too far away and catching up to them is not always easy or sometimes possible.
Thirdly, the "I wasn't in range" can be a viable argument but most of the time the halting emote is done in /s so that takes care of most of the issues but if you are still out of range, most of the time the bandit can emote once more to make sure you heard it which most of the time will be the case because rarely are you gonna chase somebody who is already 60 blocks away
