Well, botting is against the ToS.

I've played with a bot before.
Found one which would /wave to me if I got near enough.
If it ran up to a mob, I could do an instant cast and have it kill something for me.
But it wouldn't leave a relatively small area of Felwood, so wasn't too helpful in my leveling.
Still fun to play with them sometimes.

I could see a hunter dragging a bunch of mobs to the bot and then using Feign Death.
