Why "This user is protected. You may not use this tool on this user"

[vbluis]

Hello,

It means that you try to apply it for post created by moderator or administrator.

Thank you. The message is not an administrator or moderator.


But before applying spam-o-matic, move it to a trash forum.


On the move could not work?
Thank you

PS: A curiosity, which I can do if "denounced" by mistake to a legitimate user?
