As for newbies I like to suggest to give them a little bit freedom, like it's okay if they reply on threads with just a short message, or they posted similar but not exactly the same topic,.. Some
Let them learn and explore.

But when they reach and started Jr. Member rank, and they still doing the same, atleast send a PM to inform them about their wrong doing or their repeated mistakes, the next if they does do it again then give them a red mark or the negative trust with the Right and PROPER comment,
Lastly is the warning message let's take 3 warning letter with response letter like apology letter, explanation letter, 4th warning comes with a one month account band, 5th time is 2-3 months band with a fee, then lastly permanent band,.

It's only a suggestion on my part, but I am so happy if some of them Can be carried out Bearcats don't like my account just to be band with out any warning or explanation....
