As a starting point you will need to review how the community curation account is being used.

@steemit-pak has over 100K SP but only a small portion of its voting power is given to ordinary members of the Pakistan community. A significant amount of the votes go to reward Mod, CRs etc, and another large portion is used to chase curation rewards outside of the community.

If 100% of the voting power is used on ordinary Pakistan community members you may see a significant increase in enthusiasm for posting better quality cotent in your community.

You then need to work extremely hard with every member of your community constructively critiquing their posts to ensure they are producing the very best quality content that they can.

Finally a review of the management team of the community might be in order to ensure everyone is a 'best fit' for their role.
