Authored by Claude karel.kubicek.claude | privacy:requests [2026/09/21 14:55] (current) – Use in Publications: remove the duplicate which-lists table (drifting against the canonical copy on programming:filter_lists); replace with two sentences plus the pointer, and state why S1=197 and the filter-lists population=194 differ.

| Of the **197** papers that used or produced an advertising-or-tracking filter list. A paper naming several lists is counted under each, so the shares do not sum to 100%. Names were folded into families, because they are free text: the //Spellings folded// column is how many distinct strings the corpus uses for each. [[Programming:Filter Lists#Which lists|The filter-lists page]] computes the same table over a slightly wider population (198 papers, because it does not intersect with this page's request-classification task fold) and is the canonical version; the two differ by one or two papers per row, which is itself a useful illustration of how much a population definition moves a count. | Of the **197** papers in S1 — those that used or produced an advertising-or-tracking filter list — EasyList is named by **110 (55.8%)**, EasyPrivacy by 71 (36.0%), Disconnect by 48 (24.4%) and Ghostery / WhoTracks.me by 34 (17.3%), a paper naming several being counted under each. The names are free text and are folded into families before counting, which is not cosmetic: counting exact strings alone finds 90 EasyList papers instead of 110 (−18.2%) and **26 Disconnect papers instead of 48 (−45.8%)**, because //Disconnect list//, //Disconnect.me//, //Disconnect Entity List// and twenty-five further spellings are one list. **The full per-list table is on [[Programming:Filter Lists#Which lists|the filter-lists page]], which is the canonical copy** — it is deliberately not reproduced here, because the same table maintained in two places drifts. |

| **Folding is not cosmetic here.** Counting exact strings undercounts EasyList by 18.2% (90 papers against 110), EasyPrivacy by 19.7%, Ghostery/WhoTracks.me by 11.8% — and **Disconnect by 45.8%** (26 against 48), because it appears as //Disconnect list//, //Disconnect.me//, //Disconnect blacklist//, //Disconnect Entity List//, //Disconnect Tracker Protection lists// and twenty-two other spellings. Any table of list adoption built on exact strings is wrong by tens of percent. | |

| | That page runs the //same// fold — both report scripts import ''req_fold.mjs'' — but over a population of **194** papers rather than these 197, so its rows sit a paper or two either side of the figures above. **That is a property of the two membership rules, not a disagreement between two counts**: S1 is built inside this page's request-classification population and reported after its exclusions, while the filter-lists page takes every paper the fold fires on with no topic restriction and then applies a tuple-context test this page does not have, which removes five papers whose list //name// is right and whose //use// is a malware or piracy blacklist. Both are correct over what each says it covers; the delta is itemised paper by paper on [[provenance:programming:filter_lists|the filter-lists provenance page]]. |
