As part of a new push to regulate and enforce opt-out policies among web advertising companies and the tracking of web users, the Federal Trade Commission (FTC) has reached a settlement with advertising firm Chitika Incorporated over a "bug" in their software that resumed tracking users who had opted-out of their program after 10 days, The Wall Street Journal reports. The company claims it intended the opt-out to last for 10 years, but was unaware of the problem until the FTC pointed it out last month.
