It’s real, but it might be overblown. The delegation design we have allows a DSP to manage when impressions are saved. That can limit exposure to untrustworthy sites that attempt to snipe conversions.
The one thing that the IPA had over this was the ability to retroactively remove IVT from impressions. Here, we acknowledge that limitation, but that is a constraint on its (successful) use, not something we regard as a fatal flaw.
