Dear Google: please, instead of just blocking a particular number when I report a call as spam or scam, start cataloging the content of those voice messages (I know you're listening anyway; you have to in order to transcribe them) and automatically delete any more messages I get with the same content.
This is like blocking an individual IP or email address, rather than blocking suspicious-looking links on your website.
It's like whack-a-mole, except it's not fun.
