Second Life users have the ability to block/mute those that people that annoy them, both voice and chat. One can also mute objects that are spamming them. Once blocked you cannot:
- See text chat, hear voice chat, or receive IMs from that person or object.
- See particles emitted by the blocked avatar or object.
- Receive items from the blocked object.
But, muting is not fool proof. You can mute someone in-world and it has no effect in, I think, group chat, the market place or in the new social features. I don’t do much muting…
Running on the release channel Magnum is a new update that has the code to move muting from the simulators into what the Lindens call the People API’s. These are the API’s that will become the primary call for all communication tasks in Second Life. The People API is or will be queried to get the information needed to establish a communication cannel. So, it is in a perfect place to control the communication.
