Okay, lets call it semantics.
You admit you went against the rules. He called you a cheater.
mmm. Yup, I fail to see how he could not make that call....
http://www.merriam-webster.com/dictionary/cheaterYup, depriving someone of e.g. points by the use of deceit or fraud could be contrued as cheating.
Now, its real easy. You have, or should have read the rules. Ignorence is not really a defence here. Therefor what you claimed you did, goes against CC rules. You engaged in an practice that is not only frowned upon, but actually against the writen rules. Doing such a thing is therefor considered cheating. You might not like the denomination, but you should not argue if someone puts such a label on your actions. Now I assume it will indeed take the hunters some time to sort this out. Based on the suggestive chatcomments and explenation a block or severe warning might at least be appropriate. Luckely I am no hunter, so it is not my call.
I wish you better luck with your future games.
