Ghostery is problematic, I've stopped using their serivce (now using disconnect.me. Some sources say that Evidon, the company owning Ghostery, plays a dual role in the online advertising industry. Ghostery blocks sites from gathering personal information. But it does have an opt-in feature named GhostRank that can be checked to "support" them. GhostRank takes note of ads encountered and blocked, and sends that information, though anonymously, back to advertisers so they can better formulate their ads to avoid being blocked.[4]
