Just a few changes to the instructions and notes in the crucial entries.
(Super thankful for this list, it is very helfpul!)

Thanks for this! I like the suggestion for Nuwber but rewrote it a bit to avoid the term “dark pattern” as I prefer “deceptive design.” (Unfortunately I did this manually so didn't exactly merge the request; it's difficult to do this when there are multiple changes in one request so I hope that's okay; I usually like to make sure to give credit.)

For PeopleFinders, the reason I ask people to search for their information first is to make sure the site actually has it before sending them more data in a removal request.

For Radaris/OneRep, I think people should really avoid creating an account, and have removed data without doing so, but please tell me whatI’m missing!

For Spokeo, I didn’t have to solve a full captcha, just check a box. I also like the joke about grammar. And since it opts you out whether you check to find the confirmation on the back of the sign-in page, I think it’s okay to skip that instruction.

For White Pages, I’m not sure I understand the instructions. What filters does this refer to?
