Increase Spam Detection

About a year ago I found a fantastic plugin that helped me automatically detect, flag, and even suspend spammers and I am exhausted trying to find it again. The idea was something like this: You create a list of words to look for; example: win, winner contest, bank, lottery, call, phone. Then you would set a threshold; example: Using 2 words would flag the user as possible spammer. Using 3 words would automatically suspend the user.

If anyone knows of this plugin I would appreciate it if they could give me the name of it or a link to it. Also, I hope others that don't know about it yet find it useful too.
