For me, when the ad deliberately blocks the content your viewers came for and forces you to click the X buttons to close them on every page just to see it, something has gone wrong. This happens EVERY page.
People happily pay Baseball America or The Athletic $50 a year for their quality and frequent content (Like me). Fangraphs just needs to rework their entire business model. I’m not saying they should offer their content for free, but maybe provide better value and content people would actually pay for.
