blackholes.intersil.netzone "lists entrenched spammers, mainsleaze and mainsleaze wannabes who have pestered users at Intersil." The
flowgoaway.comzone lists FloNetwork systems.
The DNS lists maintained at the 4 sites marked with an asterisk ("*") were suspended after the destruction of the World Trade Center to avoid any collateral blocking of communications by the survivors. All of the lists have returned to normal except ORBL, which is why there were no hits in it this week.
The XBL is excluded from the zone union because of of its extremely aggressive listing policy, but otherwise is shown for completeness.
