I’ve implemented an “ignore user” function for the board, a feature I’ve fielded many requests for. It’s very old (3 years) with no updates so not sure how dependable it is.
I just ignored someone, and their topics did not appear. I went to a thread which they started and the responses were there, but the ignored user’s original topic was not.
So it seems to work.
Let me know if you have any issues and if it works for you.
The ignore user feature is located under the user’s profile picture in their forum posts.
