What is even more frustrating is that even after you ad negatives to your Broad Match ad groups, Google will still send occasionaly Exact Match traffic to the broad keywords. I asked my rep about it on several occasions and it was described as an anomaly...

But it happens consistently, not a very high volume but it still happens. For a system built on rules, you would think it would never happen, but it does.

I run all my exact and phrase terms as negatives in the Broad adgroups (or campaigns) as others have suggested. So far I haven't hit a limit. I currently have 50k negatives in my account, and 8k the most in a single campaign.
