The fix was to block the botnets that were scanning millions of numbers and ban the associated accounts. Likely that includes some ongoing threat detection as well. That'll at least prevent scammers from collecting one more account name/number to attempt exploiting. It doesn't do anything against a targeted attack against someone who has chosen to be discoverable. That's just how search/discovery is intended to work.
