It would look ridiculous IMO. All that seems a little unnecessary in my opinion. And even so most of "C" is too complicated for SE. A & B were good enough IMO. No need to completely destroy fishing for normal players just because of bots. The way the system works now for that is just fine. And most botters aren't going to be fishing in cities/towns, too much activity and it would look conspicuous for a single character to fish in the same spot for hours on end and not say a word to anyone.
