solovev, do you have a link to the thread that was discussing ways to improve forum spam?
I looked before I posted this message,
and I found this thread. I had not seen that thread previously.
I was talking about this thread only and I think I was not registered here at that time. If you check the replies there, most of the members contributing there are high rank members only. At that time, the new members were not concerned about the forum and were thus not giving any suggestions. Later when a harsh decision was taken in the form of merit system, we see so many threads from new members complaining and giving their expert opinion about the merit system.
