I know blizz had a sort of turning point moment on their fight against bots a while back, but I hadn't started to play again since then to see for myself. I'm just curious if they actually won the battle and bots are gone for good now (or at least the big ones?)

What's the current state of the game in regards to botting, are they still constantly at the gathering nodes all over the place, and fking up battlegrounds, or have they been removed?
