I have no authority in this matter, but I would humbly request that mu.nu'ers who are not technically proficient please refrain from making changes to the blacklist. If you can't recognize or undo a mistake, you really shouldn't be making changes that affect the entire system.
We keep getting fragged comments because people don't know the proper way to add to the blacklist, nor how to undo their mistakes.
If I may be so bold, non-technically-proficient users should just add their requested blacklist entries to a list, maybe here, and let technically-proficient bloggers add them when they can.
Just a suggestion. But the biweekly comment-outage is getting out of hand.
