Amm ur detecting so u can prevent it ? same thing to me :P
There are ways to hide ur code and a cypher can be made very easily and like u said its 2011, there are ways to hide ur code very efficiently, not depending only on obfuscation cus thats easily bypassable and im talking about the cipher with keys for the launcher to communicate with the server, and those keys are bytes those keys can be selected by u. And to even complex it more u can add byte shift operations and that kinda kills the fun for everyone trying to crack it, and no bot program can get THOSE keys it can be in number of 50 or more.
Later edit: Why would ncsoft or anyone would want to lose bots ? ppl hve auction on ebay selling adena or kinah or gold and silver. Killing bots can have dramatic consequences and + its free advertisement in alot of ways, think of it.
