I'll just post something in regards to the OP question.
It's really hard to come up with a reason convincing enough as to whether you should or should not start botting but i think i can say that if you value d3 as a game that you play to enjoy, you might want to consider the following:
-You could lose interest in actually playing the game really fast, leading to a distorted version of d3 for you to experience. At least until a new major patch comes out.
-Botting is not 100% just lay back and enjoy the incoming stream of cash. You still have to buy cd keys, create accounts, level up characters, gear them up, install the bot and all of the peripherals, monitor the bot for a percentage of the time, restart it every once in a while, update some stuff whenever a patch comes out, etc...
-You will get banned eventually. On at least one of your bots if you are running more than one. This is a controversial topic though since many people report different banning waves, methods and patterns.
-If you think you want to make a living out of it, then think again. Unless you have a serious investment in mind.
-Getting bots to work requires some (quite low) level of understanding in operating systems and scripting. Don't expect to find all of the answers on the web since its a rather controversial topic and information sources are sometimes hard to find. There is at least one forum that i personally know of which has absolutely 100% of the information you need.
I'll stop here. From a moral standpoint i will advise against botting for anyone who still hasn't started.
Edit: This is only relevant to farming bots, not ah bots.
