How can a scammer make 1000 accounts? Don't they need to give Google Store some gov ID, credit card number? If this are too easy for scammers to get then ask for more documents that a legit company or developer would have. And you can make this more strict stuff optional, if you do not provide this documents your activity and reports are treated 100x more seriously.
My suspicion is that companies are using AI crap to handle user reports, some devs very exited to work on this cool new tech where they can replace even more people in support and QA with scripts.
