Maybe your ad blocker isn't as thorough as mine
I can read it on this tablet I see as the big banner moaning about ad blocking scrolls up but on the laptop it wouldn't. I'll recheck that.
OK on the laptop I see 2 scroll bars. One just moves the ad blocker complaint up and down a bit and the other scrolls the page behind it. There would be ways around this but I can't be bothered as if desperate to read something I can set the pihole to be disabled.
Notice in the bottom picture that the pihole is blocking 32.5% of all requests. Just shows how many ads there are.
