I have recently become overtly infuriated with personal data distributors and hope to make other peoples' lives easier in giving guidance on opting out of sale of your personal data. Please keep in mind that none of this will ever substitute 1) personal data protection (i.e. keeping your information out of the hands of data brokers in the first place) and 2) the complete dismantling of this, frankly, fundamentally evil industry.
This site is under construction, and it will take some time to get the ball rolling. In the meantime, try googling your name and opting out of whatever you can.
