An ad-removal userscript for tsmnt.com: pins the visit-frequency cookie, sweeps the layered ad-loader chain from the DOM, and blocks cross-origin popups. Targets the random popunders fired when clicking "next page" plus the in-page ad slots. Works on desktop and mobile.
analysis/)js/dh.js: increments the `visits` cookie on every pageview (the frequency gate)
├─ js/vtj.js -> (desktop) js/pc.js
│ └─ on paginated pages (URL contains _), when visits>3, randomly loads
│ vdn/hi1-4.js (even visits) or vdn/cpv1-4.js (odd) - the click-
│ triggered popup engines ("next page" randomly opens an ad page)
└─ cdn/pic.js -> (desktop) vdn/gd.js
└─ when visits>4, injects a gummy-debt.com script (Monetag-family popunder)

Images and pagination are plain <img>/<a> in the static HTML; no gallery script is required for normal browsing.
| Layer | Approach |
|---|---|
| L1 cookie pin | At document-start, set visits=0. Every ad loader reads this cookie before firing, so all gates stay shut even if a loader slips through the sweep (dh.js is swept, nothing re-increments it) |
| L2 script sweep | Debounced MutationObserver full-document sweep with a blacklist of regexps: /tsmnt/a[2-9]+.js (a1 kept), /vdn/gds?.js, /vdn/(hi|cpv)N.js, /js/(vtj|pc|dh|fp).js, /cdn/(pic|lam).js, /sa/mcpcN.js, gummy-debt.com. Path-based matching covers js. mirror rotation automatically |
| L3 popup guard | Wraps window.open, dropping cross-origin popups (ad landing pages are always cross-origin; the site navigates via native anchors) |
Trade-off (accepted, documented): sweeping the a8->dh.js chain also drops the favorites feature (scj.js) and the translate widgets; the fingerprint tracking and stats pixel disappear with it (a privacy win). Image browsing and pagination are unaffected.
