Hey all, Looking after a locksmith client where we're getting a lot of spam calls to our call only campaigns. It's fine to deal with this on our desktop campaigns as we can just block the IPs who spam click our ads, but on the call-only campaigns it's a different story, as Google refuse to block phone numbers. Anyone have any ideas of how we can deal with this? We're under quite a bit of pressure from the client to stop these so any suggestions would be appreciated. Thanks.
