Block, unblock, block! How ad blockers are being circumvented…
summary
Claims that at least 6.7% of top sites use circumvention, and that an anticircumvention filter list updates hourly to push countermeasures. Demonstrates concrete tools: community filters plus JS snippets that abort on property read/write, a developer‑tools trick that fools circumvention into self‑revealing (worked until patched), and a PNG data‑URI fingerprinting method to detect superfluous element stuffing. Shows ongoing cat‑and‑mouse: filters deploy, CV providers change content, filters adapt again.
