Even if the bot program is used for leveling up a character with no intent at farming or monetary gain, it still shouldn't be allowed. The whole point of an MMO is to put time and effort into your character to get to the state you want it to be in. Not hire cheap computer labor to do it for you and cheapen the efforts of people who actually enjoy playing the right way.

In the old FFXI days I saw people actually selling max level characters with full relic gear to any scragg who would buy them. It really is a slap in the face to the creators of the game and us players alike when you have people like that running around.
