Instead of completely restricting newbies from posting in the lending sub board, their posts containing loan request should be deleted instead that is users can report newbies requesting loans to the board mod and the mod deletes that posts
. It's not possible for Mods to keep tracking a user and check how many times he created a thread or posted on a specific topic and asked for a loan. Also, It's not possible for Mods to respond quickly or instantly to delete such posts. It will increase their workload. Moreover, It's nothing compared to bounty boards. But, the community members care about this section because it is a severe section where people look for urgent money, which sometimes helps them survive. Trolls in such sections will ruin it.
The restriction might come if the user keep making such posts. My reason is so that if a newbie has any valid contribution to make in the lending sub board their rank shouldn't be a hinderance.
Have you ever seen a newbie Lender offer loans to others? I always see newbie accounts ask for loans without any forum history. They do not intend to return the amount if they get the loan. They will lose nothing if they don't repay the loan amount. Also, It's not possible to catch them if someone runs away with crypto money. If a newbie has a valid contribution, earning ten merits for his contribution is not very hard.
