Since many of these deep conversations are spammy or tangential to the topic at hand, a feature is needed to either split off the threads or implement a sub-thread ignore. However, other portions of the thread are still relevant and should not be ignored. Reproducible: Always Steps to Reproduce: 1. Subscribe to the comp.lang.java.programmer forum. 2. Download messages from the last few months or the last ~ 2 thousand messages. 3. Look at the thread entitled "Java and avoiding software piracy?" or "Java 7 Features", especially replies from "Twisted" Actual Results: Lots and lots of annoying attack/counterattack posts cluttering up my view and new message counts. Expected Results: The key posts would be marked as "Ignore subthread" and those posts would be treated as ignored.
