Exclude specific user from specific topics

Is it possible for users to decide to block a specific user from replying to their topics if they want ?

Case of user who troll on specifics topics, don’t want to ban him from all the forum, but should be great if users (and moderators too) could ban specific users from their topics.

If this person can’t manage to behave themselves, why wouldn’t you want to suspend or ban them from the entire community?

Either way, ignoring individual users is something we plan on building into the next version. So rather than preventing posting, someone can choose to not see replies from a specific individual.
