The state registry is the system of record for every sex offender record here
Every record on this site is a copy of what one state registry publishes about a registered person: the name, the photograph, the offence, the address and the date the state last showed it. The state that registers the person decides what is published, changes it and takes it down. We show that listing with the state named on it, and we re-check each registry continuously.
That is why the fix depends on which of three things is wrong. A record the state has already removed is corrected on our side; a record the state still publishes with an error in it has to be corrected by the state first, and our copy follows. The three cases are below, with the form at the end.
