This kind of clutter is never harmless.

The more of it we get, the harder it becomes to spot anything really malicious in the welter of cookies, super-cookies, widgets, trackers, adverts and redirects that make using the web into a rodeo-roping contest with herds of space aliens.

Mudcat is completely unusable without having a lot of this stuff blocked, and we get no help in deciding which of these gizmos has to go.
