How to block iframe on a specific site?

Question

Ad blocking

Literally today I encountered the problem of blocking the iframe, tk. none of the ad blockers on chrome.google.com/webstore/ could block ads in the frame, and google started to get dumb. The simplest solution was "javascript always block on this site", are there any softer options? Adblockers are powerless on these sites kp.ua, korrespondent.net
