A letter addressed to the Ask.com Chief Executive said:
"After a more careful review of AskEraser, we have found at least three significant flaws,"The letter was signed by Marc Rotenberg, executive director of the Electronic Privacy Information Center, and many others. The flaws are believed to be corrigible by the privacy advocates. Further, since the stated objective of AskEraser was to protect customer privacy, hence the features of the new tool should also match with the stated objectives.
There are three problems which have been identified. Ă˘â‚¬Ĺ“The first one is the fact that AskEraser uses an opt-out cookie.Ă˘â‚¬Âť In the present scenario a wary user usually deletes cookies, so if Ask makes use of opt-out cookies and once the opt-out cookies get deleted the privacy setting would no longer hold and the users activity would be tracked. Hence it makes this measure "counter-intuitive." A better option would be to have an opt-in cookies, as has been suggested.
Another issue is "Ask inserts the exact time that the user enables AskEraser and stores it in the cookie, which could make identifying the computer easier and make it easy for third-party tracking if the cookie were transferred to such parties." Consequently, to prevent the privacy of a user if "a session cookie that expires once the search result is returned" is made use of then it would solve the problem.
