Why this visa harassment?

Few days back I along with my friend went to the Malaysian Embassy at Baridhara for submitting my student visa. We saw a notice on the notice box before the entry gate that read "Malaysian Embassy will not receive any individual student's file till further notice". We asked the gateman what we should do. He told us to contact the Malaysian Embassy's tourist agents for dropping the file at the deposit counter. We contacted a few enlisted tourist agents and were informed that it could take more than three months to get visa approval with extravagant amount of agency fees. We waited in front of the embassy gate on the two following days. On those days we observed that the gateman allowed some people to enter. After seeing that, we went to the gateman and asked him to allow us in. But he refused and told us to seek recommendation from any embassy official. Finally, on the third day, during the embassy opening hour, one Malaysian gentleman (embassy visa official) came out and took a few students inside including us and that time he explained that some officials were doing “dodgy business” there. Even he received our individual student file in a friendly manner. So what is the point of this type of harassment to student-visa applicants?
