General users should be prohibited from posting. Because there are many scammers among the general users who are cheating the customer and stealing the customer's money, the customer is being harmed, so the general users should be banned from posting ads in Bangladesh market. And also note that even though ordinary users can post ads, they also have to pay a security deposit so that if the customer is cheated and appeals later, his money will be refunded and this is what should be done.
