There is not always a trusted member behind a Legendary account, nor Newbies are always scammers. It's not the rank you should consider when lending, but other things like collateral or other loaning principles that I might don't know. Because, even though account sales are discouraged, but they are still happening in the hidden (mostly in Social Media) which means that even a new member can come up to you with a very high ranked account to ask for a loan with the hope that you might consider his request seeing the rank he has on his account. But never do that mistake. It is always better to double check than regretting later.
I hope you don't get scammed.
Good luck!
