How much you like the idea of implanting captchas to irc ?
Of course if would prevent non-graphical terminals and bots to connect, but this would be the end of mass clones attacks.
Just want to know what people think about this.

IRC is by nature a text based protocol so there would be no way to send CAPTCHA images except via DCC and since for security some people will have DCC turned off they wont recieve them.
Another point being is what about JAVA clients that dont support DCC again they wouldnt be able to recieve the CAPCHA image.
Personally i believe CAPTCHA cannot be added to IRC itself.

The ircd would not generate any image, but only a code or an url.
And the client could request the picture on a web server.
Almost all Java clients are setup as web applets.
Well I assume that admins who want to get rid of clones attacks would run an webserver, and to me there's only technical issues for non-graphical users, but not over the web.

You could host the CAPTCHA image on a web site but how would the IRCd be able to know that the check is sucessful and is from the right person.
Personally i cant see this working.

The ircd would generate an url or a crypted code. Then the web server display an image, and finally the ircd wait for the proper code to be typed by the user.
That's the ircd which valid the connection.

Then surely the bots would eventually be able to find out the code to be typed from thr URL given by the IRCd.

I don't think so mate
Any other thoughts ?

You dont think so? There are many programmers out there who'll disagree.
