Thanks, this is very useful.

The paranoid voice in my head is wondering if these forms don't actually opt me out of anything, and instead just confirm to these companies that the information they have on me is correct.

The LexisNexis link 404s (added a space), I believe this is correct:

Also, the following can't hurt:

+1 Thanks for sharing! If anyone's actually found these to work please share so we can get more confidence in them :)

The Epsilon link 404s, but I think this page is where it should have gone: https://www.epsilon.com/en_US/consumer-information/consumer-...
