I did an experiment with an alt to verify that blocked avatars could not interact with scripts in worn objects. I was shocked to learn that they can. I wore a spanker, blocked my alt, and had them click on the spanker, which responded to the click just the same as if they were not blocked. That was not the expected behavior, and it should not be the intended behavior. Blocked alts should not be able to interact with scripts in objects owned by people who have blocked them even if the objects are not worn.
