I am guessing Sajha is getting less conservative and trying to cover most of them. As the thread is opposed by most visitors are deleted.

The point is if you ask genuinely " help please" , not even 200 people will look at it and the content it self. That is the only way to get attention and sometimes the heading and the contents are quiet opposite. Long time ago I copied and paste a highland lace which was in one of the tracking or ticketing agent. It was true natural beauty but people had their own comment depending upon their level.  That is what sajha is and as the crowd increase we will be heading with it.
Example :  hijoraati uslaai dekhe sapanimaa" it is just a  waste of time even to open it.
