With "not civilized" you mean "don't agree with me"?
I like the subject, but I think we can all be more friendly here.
And about the 300 million people, it is not as if these people are all visiting your page. It is a small percent of the total active internet users, so revenue should decline with less than 1% I believe.
The question I get from this is: if you see a revenue drop of let's say more than 10% and then make sure you won't show a blank page with ad blockers, will the rev get back up with 10%? I am curious if anyone experienced this.
For me, it would be surprising if ad blockers really take away more than a few percent of the revenue. For Facebook and Google this is obviously a big deal since a few percent is really a lot to them, but for parked pages, I assume it is mostly not that big of a deal (although any money loss is not ideal obviously)
