Why continue to complain at this point?

[Zanshin7]

So what is the point in continuing these complaints when they are not going to change anything?

When people are frustrated, they need an outlet.
They can either go do something else or they can complain here.
You make a mistake, be prepared to hear complaints. There's no way around it.

Now, what should be done is the moderators (if there are any) should merge all the complaints threads into one giant thread. People would keep complaining but it would be contained and if you don't want to participate you can just avoid the thread altogether.
