Title. What is the difference between these two actions that can be performed on users and communities?

you are viewing a single comment's thread
view the rest of the comments

My understanding:

Blocking a community will stop you from seeing all posts from said community.

Blocking a user will stop you from seeing posts and comments from said user.

Filters will stop you from seeing posts with specific keywords. For example, filtering "Trump" should stop you from seeing posts with trump in the title. But you'd still see other posts from a community, like politics.
