I've been told, which is correct, that adblockers that show you the number of blocked ads on a page are also counting tracking widgets, social media, and other things like that. For example, on the Ace Combat wiki, we have a Twitter and Facebook widget on the main page. These are blocked by my AdBlock, and add +2 to the count. Lots of other things are blocked, not just the visual ads, so the 31 count you're seeing is heavily skewed. It's probably closer to 5, maybe less depending on the page.
