FC: 7 tips for limiting data collection
1: Do not provide email addresses to mailing lists unless you need to do so.
2: Unsubscribe from listserves or sibsites that you do not regularly use.
3: Limit the number of times you click on ads, no matter what they are for.
4: Avoid "too good to be true" products, deals and opportunities. Once you have confirmed your email address, they are likely to sell your email address to other companies.
5: Disable Internet "cookies," so that companies cannot put tracking devices on your computer.(Sites will not be able to remember your preferences as well this way, which is something to consider.)
6: Investigate computer applications that block pop-up ads.
7: Examine sites' privacy policies before you reveal any information on the site; avoid using sites that will share your data with others.
