Crypto. com and BlockFi are not giving up rewards

I have noticed that everytime these two ads pop up on their rotation that the reward numbers never add up. I have clicked 17 times today on the BlockFi link that pops up and not one time did I get a reward added to my monthly total. This is the same with Crypto. com . What is the purpose of advertising these sites if they are not going to pay rewards. Or is this a issue with the Brave platform itself. It seems every other link works just fine. My settings are set to receive 5 ads per hour but I never get that from these sites.
