Aren't the MMORPGs also at fault? By requiring a long, boring "grind", they are encouraging players to automate their gaming hours. After all, we play games to be entertained, not to repeat boring tasks.

That's a good reason why this activity (writing bots) is not seen in a negative light even if it may cause problems for the company running the game and/or other players and the game economy.

The repetitive tasks are the fun aspect for many people. If it isn't fun for you, you have two choices: Either quit the game and find something you actually like, or use bots and ruin the fun for other people that like the game.

Not every bot ruins the game for other players.
