Wow, that was not made clear to me. Fortunately I've never needed to block anyone specifically from my profiles/content (it's the other way around, I don't want to see some other users stuff)

But good to know if I had a stalker or something, blocking them doesn't mean they are blocked from my content, it means they're blocked from contact.

I totally would have assumed blocking someone on various social media platform went both ways in terms of what's visible to each other.
