Only a day after the new chat implementations and spam filters have been put into place and already the bots have managed to overcome this issue. The new spam filter checks the message and compares it to previous messages to notice a patter, there by blocking the bot from posting the same message over and over again. There already have been multiple bots in the chat that overcame this new restriction by generating a random string of characters at the end of each message to fool the spam filter into believing it is a different message. NCsoft did a great job in the implementation of a spam filter, but the bots are evolving and to combat the ever changing spam, NCsoft also has to evolve it's spam filter.
