My theory is that when the Ed is not in the office the system is set to auto suspend following maybe one, maybe several reports. I think one of poodis comments may have been reported and auto suspended. The night she and welsh were suspended they had not typed anything worthy of suspension as it was merely bickering. Of course if someone reports them they would then be suspended and once the Ed got into the office the next day and reviewed it , reinstated them.
My concern is that users may abuse this system and start maliciously reporting people they are arguing with in order to suspend them for the evening. Of course if the Ed looks at the reporters he could suspend them for abusing the report button function.
