Well the site I was going to post is another website not for the bot itself but it can be found there.
Can you get banned using a clone hunting bot? Yeah probably.
Do I know of anyone who has? No.
There is an older version of DC Sitter that uses an autoit script to create games, (i think its sitter anyways) and it is probably the (safest/undetectable/whatever). The only drawback to using it is you need a seperate install per cd key that you want to hunt on. (edit you might be limited to ONE key to hunt with with an autoit based bot because it probably won't run minimized.)
The more elaborate and powerful bots can just use different mpq's and run from the same directory.
The bot the serious hunters use include anti-idle code variable game creation delay and a few more nifty tricks, but I guess the question you have to ask is do I want the extra speed/features etc at the cost of more visibity to blizzard. As for if they are looking for ip bots atm, who knows.
*EDIT*
Most hunters do NOT hunt with their main account, just an un-nessacary risk. If you have a spare cd-key (or 10) g-rush yourself a few characters (on seperate accounts) to hell and use them to hunt with. Then once dclone takes a walk use your pally to kill him. This gives you a character to kill with and one to pick up the anni with. When you get into hunting you are only limited to how many cd-keys/ip addresses you have. (4 without a proxy, but thats another subject.)
Ok I got confirm this was ok, if you are looking for more bots and clone hunting in general you should visit
http://dcloneirc.net if you don't have irc then there is a java client so theres nothing to download, anways swing by the #useast-dclone channel (or west if ur west) and the #bots channel for more information.
Look me up when you get there.
