I do not know any lender who delete loan request either the loan request approved or rejected. The post has been obviously deleted by you.
In darkstar_ loan thread, I can see 47 posts have been deleted of 43 users which I think deleted by darkstar_, I do noy if they were loan request or some spam off topic reply. It is possible that darkstar_ has deleted but to be sure, PMing darkstar_ would be good.
I delete all requests that don't meet the minimum requirement since there's no point dealing with people who can't read:
2. You must have a minimum of 25 earned merit to apply for a loan. I delete all applications that do not meet the bare minimum requirements.
In Kisleav's case, I archived the post, left a neutral and then deleted it from my thread.
