It is being encouraged (by some companies such as DoubleClick Bid Manager and overseas DSP) to have an authority by “ads.txt” for the inventory, if not, it would be likely to be excluded from the bid. (starting from the end of September, 2017)

However, the digital advertising industry could achieve the qualitative development as long as all of people who are engaged in this area try to discuss the ad fraud consistently each other.
