What did Mike do to stop the spam? (and can we have it too)

Looking at it with the bot's eyes I can see two numbers: six and fifteen.

15-6=9

What to do with it?

Speaking from a coders point of view a bot can easily answer that question. It is fairly easy to do any type of math with a bot. Most languages you could simply parse the whole thing into a variable and not need any real additional code to get the answer.
