Appreciate clarification about the 'block user' function:

1- Will I no longer be able to see their posts, profile, or any existing messages with them? What if they post in a community that I moderate, will I still be able to see their posts?

2- Will they still be able to see my posts and comments on my profile or in communities where I participate, and can they reply to them?

3- Will they receive any indication that I have blocked them?

4- If I already have a conversation thread with them, will it remain in my inbox, and will they be able to continue the conversation?
