If you own your own web servers and have minimal clawbacks, what are you doing to prevent the clawbacks. I have never had a major issue with clawbacks until the past 2 months.

There is nothing unusual with my traffic nor with the number of ad clicks, so I am wondering if there is a way to determine why this is happening, which of my 10 or so websites have the invalid traffic, and what I can do to prevent this.

As you know, Google provides ZERO transparency with clawbacks.
