You're replying to the shitty threads. You have yourself to blame. If the thread is filled with nonsensical posts and is littered with zero-value posts, do you really think a reply will contribute to the lack of a discussion?
Posting to a zero-value thread is essentially the same as making a zero-value post. You should be happy that spam megathreads are closing.
And why are you so anal about your post count? If it's activity you're concerned about, you should have obviously posted quality content within the 14-day period that wouldn't be likely to be trashed, right?
