Truth Now LLC puts four domains on one California filing, this being one. SealedRecords and Check Secrets are two of the others, and turning up on one generally means turning up on the others. The fourth domain on the filing is spelled inmatesearcher.com with a single "s", which is a different and unrelated site from the InmatesSearcher we profile. It looks like a typo in the filing, but nothing on the record confirms it, so treat that one as a separate job rather than a filing sibling.
One filing is not one opt-out, though. Every domain posts its own form to its own address. Set your expectations before you start, too, because only SealedRecords can be completed the way this site can. Check Secrets refuses every request its form receives and needs a written one instead, as does the two-"s" InmatesSearcher, which shares this platform without sharing the filing.
