False bannings galore.

What other reasons to be at that map, interacting with said NPC other than for an exploit? While it is fun to visit old places, it makes little sense to fiddle around in a starter area.
If they just up and banned any IGN that entered the map from date X to date Y, then ok, that's bad, but I'd guess they have more meat on the bone than that.

Nexon hasn't released what criteria they blocked players over, so at the time being there is no assumption if they based it off the function discussed above, interactions with NPCs, or what. Mot really what else to say, the whole situtation has been scary for me to deal with.
