Researching my name, I found incorrect information on the INTELIUS website. I contacted customer service and inquired about correcting the matter.
Even though they input the information on their website, the claim is that they CANNOT change what they have posted, and that I should contact the agencies from whom they acquire the data. Who are they? Of course, they aren't sure or don't know. Needless to say, in addition to listing an incorrect spelling of my name, they also have me linked, as a family member, to people I don't even know.
Having the same last name does not mean people are related.
Needless to say, since they chose not to make corrections, then I have to believe that the site is unreliable and should not be used as a primary source of background check information. Look for a more accurate and reliable source before spending your money.
