Mute resident (and their objects) is great. Its a very good step towards griefer control. The new land based push controls are even better.
However one thing still remains, Griefers and jerks that like to run around sims (usually with offensive avs) just being a general doofus to everybody around.
I was at a club this weekend when a guy was running around pushing (those days should be over) and waving a flexi prim penis larger than his body at me and a bunch of other women. No one was on to ban him so we had to accept it or leave.
I suggest in addition to "Mute Resident" we have "Hide Resident" as a personal option. It should hide the av and all the prims / particles he/she rezzes or creates. This would allow us to truly ignore idiots and even create our own instances of certain places. This could all be done client side on a per user basis.
Whats the fun of taunting someone that cant see you?
