For years I've use and have sent many (lots of) people to https://www.annualcreditreport.com/cra/index.jsp
for an anual credit report. In the US your allowed 1 free credit report a year. Three companies are sent
request, so one is able to get 3 reports a year or one more extensive one.
Experian is one of the three companies your request (and information) is sent to. I would imagine
any info I've sent them is now public domain.
Of course I've read the ToS of annualcreditreport https://www.annualcreditreport.com/cra/helpprivacy
it was all good, and still reads that way, till the very end: Last Updated November 15, 2006
I would think there would of been some changes by now.
Not sure if due to "Experian Sold Consumer Data to ID Theft Service", but there's a banner now that says:
