I know levels don't really mean anything in this game, but there are a few out there that would love to have higher levels.

Since the fastest way to level is donating giants, I was thinking of a botting function that does just that.

It would be kind of a dick move, but:
1) Train giants
2) Join a random clan
3) Donate giants to all open requests
4) Leave clan
5) Rinse and repeat

It would be a lot easier to join a botting clan, check the clan discussion subforum here. I recently joined one and donated 1200 archers in 12 hours
