In Cordova there was some annoying shouter/giver harrassment script that seemed to be a constant name/object mutator, in order to avoid muting/ignoring.
As far as I can tell it would shout/give, then immediately rez a new version of itself with a new randomized name, and quickly deleting the previous version. This made silencing it impossible since the mute list could only show the names of the old objects that had shouted and removed, and the "Ignore" button in the 50 dialogs were also useless.
Therefore I ask the Lindens to give us an atomic bomb of sorts to silence these mutator griefing scripts, no matter what name they have changed to in the last second.
Have the Mute window retain the key of all the objects that are shouting or giving stuff, and give us a button that says "Mute all Owner objects". Then use the key to find the owner and to silence all objects by that owner in the sim.
A "close all open dialogs" would also be useful to clear a stack of 50+ waiting spam dialogs from such griefer objects, though this could be a part of the muting of all objects by the owner. Mute all current and future objects, and close all waiting dialogs from objects of this owner.
