Lets face it, there are a lot of people who's posts you can live without. To make this easy (and to cut down on the drama), just use the forum ignore feature.
Step 1: View their profile.
Step 2: Select "User Lists"
Step 3: Select "Add to Ignore List"
From now on you won't see their posts (unless someone quotes them, not much I can do to help you there).
Enjoy a better BCSB experience.
