Then you would change into a muted wolf yourself, it would be slow and painful. Much like the film "District 9" only as a wolf.

You must get bitten by the lead wolf . Sometimes, he'll come by your house at night.
If you are muted, than you can only talk with quick chat.
Don't swear then.
If you are "permanently" muted, then there is no way to become unmuted. You should have just followed the rules and not gotten muted in the first place. They are very simple rules, and easy to follow. Now your only choices are to only talk with quick chat, or to start a new account. Hopefully you have learned your lesson.
When your sim gets bitten by a vampire, it will take a few days in sim time until they turn into a vampire. They can have special powers like reading minds that you can only do at night time. If your sim goes outside a small icon will appear saying the they need to go inside before they burn! You can have babies but they will be a human not a vampire baby.
