If a certain poster is posting things that you don't want to read, add him to your ignore list. That's a better option than flaming and drawing a warning or ban.
Have some changes been made to the "ignore list" module? I tried that in the past and it ignored
the posts by the offending poster to the extent that the forum page told you that such-and-such poster had made a comment. You could go ahead and read the comment by clicking something.
I used this previously and was surprised at my own behavior. Whenever I found that some user I had "ignored" had posted something, I just had to read it regardless of whether it concerned me or not.
Maybe I would have grown into it if I had ignored more than just a couple of posters but TBH, I'm no longer using it.
