Is there a way to stop friend requests without using /busy?

If there is one thing that will make me leave this game, it's all the bots that spam me to no end. I repeatedly have a bot send me a friend request that I decline only to have him immediately send me another one.

There are ways to detect and shut down these bots. It's been proven in other MMOS. Blizzard recently banned about 200,000 bot accounts and it wasn't near as bad as it is here. Some of the bots that people were banned for were claiming to be undetectable. The truth was that Blizzard just hadn't decided to go after them. I love this game. I just bought it a couple of days ago after my trial account expired. But I have already had to set it so that I no longer receive Tells and now I'm looking for a way to shut down friend requests because the company won't go after bots.
