Same thing happened to us. We were large enough to have an admob rep who reached out to the IVT team for help. After our first appeal was rejected, our rep negotiated a second appeal attempt but he said “This time make sure you take full responsibility for the IVT getting through.

Funny part to me was Google was the only network bidding on these bots while others must have detected something and stayed out.

We submitted a second appeal taking full responsibility plus providing a long list of corrective action we took in house plus a full triage of what happened.

They again rejected our second appeal with no feedback.
