@gaypraha2: While I completely understand your point of view on the subject, there technically has not been any breach of the rules by this topic continuing to grow. As a general rule, we only lock threads when there's a breach of the rules. This gives all users a fair chance to reply to just about every thread that has ever been, with some exceptions.
As I was writing this, I just thought of a great suggestion for the site features and requests section… In the forum software, there is an option to ignore certain forum boards. Wouldn't it be great if there were a way to be able to click on an individual forum thread, then when discovering that it's not a thread that you're interested in, click a button somewhere to make that entire thread just disappear to you?
On that note, wouldn't it be great if when you decide that you no longer wish to see any content posted by a particular user, you could click a little button somewhere in the post (like in the bottom corner) to mute all forum posts from that user? This would add an extra layer of privacy for some users who just do not want to hear from a particular user anywhere in the forum, rather than having to ignore the entire forum thread.
