How long does it take to remove me?
Every information broker handles things in their own ways. Some remove you immediately, some within a few days to a week, others a month or so. It all depends on who you're dealing with. It is important to note: these companies never rest. They'll keep looking for new sources of data to publish -- and they'll publish it as soon as they can.
If you opt-out and new public records are created, a new profile for you will be created. That's why it is important to check on the aggregators once a quarter and the individual sites once every six months if you don't do it once a quarter.
