In the meanwhile time he was not active in this forum,anything may happened to him like he lost all his savings on bets or to the borrower who got never paid or whatever the reason maybe.For that calling him as a scammer is not appropriate until he did that.He is in need of money looks like because he only asked for loans on his recent posts.
I suggest you to not to give any loans for him until the already lend money gets repaid,because he might not be able to repay them in my guess.
He is not posting anything except asking loan, which refers to something wrong too. His recent days passing only by asking loan. No legit user take loan such a way where the first small amount then increases the amount. If you can find out 100 people like this then you may find out at least 95% loan default.I suggest you to not to give any loans for him until the already lend money gets repaid,because he might not be able to repay them in my guess.
