Try a 72-hour block 

There could be lockout on our own Weather Channel staff for 72 hours beginning on Sunday May 7th at midnight.

If they were involved?  Perhaps, we could restirct access to Wikipedia from their computers at The Weather Channel at midnight on Sunday, and block their IP's, which they will not edit The Weather Channel and Intellistar article again, I apologize for the trouble that has happened. - Local on the 8's will continue to air during the lockout after Sundays until it expires in 72 hours.
