It's harder than you think

I explained it here

It requires too much "lag" time to filter for everything, because the bots just change their tactics faster than a human can. Make it too aggressive and then it gets too many false positives, making people demand that it be turned off. To prevent "repeating", requires a keeping track of everything the bot says. But since they keep making more bots, it has to be tracked server-wide (if not data-center-wide.) So stuff stops looking like it's repeating when they shuffle the positions in the text, and rotate out cyrillic and greek characters.

And it's been stated before, but the Japanese servers, and the Legacy servers don't get nearly so much spam, so the problem is inversely proportional to the popularity of the server.
