From what I know, there are two different types: ignore and block.
Hence, a blocked person can post on the blocker's thread. But since they can't technically see the post, they won't be able to directly interact with the blocker. However, they can still make replies to everyone else on the thread. For example, I can't see any of Dest's posts here since I blocked him, but I'm still able to make replies to Hilmy and others.
- "Ignore" will hide any contents from those who are on your ignore list, but they can still read your post.
- With "block", neither of you can read each other's posts.
Interacting with others in a blocked OP's JOURNAL thread is what makes current block function useless. Nobody starts a journal thread wants to see blocked usernames on your journal with side convos that you're not part of and likely derailing the topic.
Just having this function work only in journal section is best.
But doubt @Baron will care enough to implement.
