So, I simply asked Google for an official statement over my Adsense Click Safety. Here is their answer. Or lack thereof :)
Thanks for your email. While Google encourages third party software development, it is our policy not to endorse any specific product at this time. We're therefore not able to comment specifically on the software you've noted.
However, we recommend that you read through the AdSense Terms and Conditions (https://www.google.com/adsense/terms ) to ensure that your software is not in violation of any of our policies. You may also wish to review Google's Software Principles, found here: http://www.google.com/corporate/software_principles.html
Basically, you understand this answer does not change a lot the way I see things.
Let me make things clear : this feature is a TOS violation. However, I have the strong feeling that breaking TOS with no side effect, but reducing click fraud you might generate, is not very questionable, while accidentally click on one of your own ads is probably much more likely to get you in trouble. I can easily imagine Google banning someone from their Adsense program because of the latter problem, not because of the first one.
In other words : use at your own risk :)
