Solution to Botting and wrongful banning for Botting

I have a simple solution that would prevent botting and would prevent wrongful banning of people botting.
This would be the use of security codes, like the ones found when you register for a forum to prevent auto registration. These codes would kick in at the same time the anti farming code kicks in and would continue to appear at random times until the character stopped repeating suspicious actions. Anet could then get reports on those who continue to get the codes wrong and ban accordingly.

Sounds like a hassle for just plain old farmers who are not bots.

What about people that have trouble reading those obscure codes?

I could see this being programed into the bot.

I don't think it would fix the problem.

/notsigned. Would be the most annoying thing ever.

Why doesn't anet just go to elona (in tyria) or ToA and ban all the monk warriors using only W A S D movement? That'll scare em ^^

Sure, captchas on /websites/ can be done automatically, but that's because the content on a website is downloaded in image format to the computer concerned. Any Guild Wars equivalent would not suffer from this flaw, and it would certainly be a lot more effective (and a lot less unfair to human players) than the current flawed system which seems to hurt players and ignore actual botters.
