what i suggested was a captcha system like emails have where you enter either 2 words or as its a game id say a mixture of 8 numbers and letters before you join a battleground you have enough time to do so aswell.
having this feature will stop bots since bots operate mainly through the night to farm for gold sites to sell high level armor for real cash etc so if they had to enter say a random letter and number 8 digits long say 8UTr12nV it would change on the next bg to something completetly different kinda how your authenticator works now but for inside the game.
Ialso suggested that blizzard do a ban wave of botters and post it on there homepages to strike fear into these lil kids who think its ok to BOT the problem on mmo champion is some people openly admit they bot here well those players shud be banned and can rot in a hole for all i care.
