“Before choice” and “after reject” count companies that can follow you across sites. Tip: press / to search. Drag a column border to resize it; double-click to fit.

Observations from one location (London) at one time, homepage only; ads and banners change between visits. Some requests after rejecting may be strictly necessary services. Nothing here is proof that a site broke the law.
