The releases with ads are often CAM or TS releases which are recorded at the movie theater with a camera
At least torrentgalaxy marks ad-ridden releases with a small red “ad” label which i filter out with a ublock origin filter torrentgalaxy.to##.fa-adversal:upward(3)
On other sites releases with ads might have the advertisement in the name like XBET
I’m usually not in a hurry to watch the newest movies so i wait for the webrip/dl versions of which the highest seeded versions have an extremely low probability of containing ads
