I say nay. Better that the moderators pay better attention to some of these posts and wipe them out. All of them.
That would be a viable alternative. But maybe a compromise might work too. If a player wants to speak his or her mind, even if it's not a productive thread, I say go for it.
That is, until it becomes disruptive. Until now, it's been easy enough to ignore certain threads. You could just look at the title or alias and not open it. Now, the essence of the whole thread has been put into the title. Harder to ignore. They might have some entertainment value in a "look at the trainwreck" sort of way, but when it's the same train running off the same tracks, it gets old. Limiting the titles to a single line could return us to a more user friendly environment.
