Is it abusing the forum?

It is nice to see people post feedback for others. But most of the feedback seem to be not very helpful. Some people are having serious concerns now and would really need some constructive and really useful help.

Question for the hosts: For those who just want to show how "smart" and "humourous" they are, are they abusing the forum and wasting the space here? Should we try to maintain a high quality forum?
