I have been trying to think of a simple and achievable way that Blizzard could create a relatively bot free environment.
1. Human character dies in BG
2. Goes to Graveyard
3. Wow displays a 5 alpha captcha on the ground
4. You type it in
5. You resume play
1. Bot character dies in BG
2. Goes to graveyard
3. WoW displays a 5 alpha captcha on the ground
4. It doesn't get typed in
5. After 30 seconds of not rezzing the bot is kicked from BG.
Note 1 - the captcha isn't displayed via a popup, but is displayed in game so that it may require you to use the mouse to move your PoV to see the characters.
Note 2 - Toons booted from BGs using this method are not account penalised, but are not allowed into BGs for 30 minutes (aka deserter debuff).
Looking for feedback on if it would work (in game terms), as it would be something fairly easy to implement in programming terms.
