Re: type a captcha after you send a message on eMule
its been in since .49a, its to stop GPL breaker mods that automatically send spam through messages.
btw, both clients have to support it, so to send a message to the client with captcha, you also have to have a supported captcha, thus, this blocks other clients without catchpa, not just spam bots,
Shareaza, MLdonkey, aMule (its a feature request), and some others.
