You are a member and you don't know that without collateral you cannot get the loan.
If you can provide a valid collateral then I can fund you.

Any collateral? Without a collateral you can't get a loan that size (especially when your personal message says "need donation" complete with address).

where the signature ? it's not a valid signature, the valid signature must be like this

now you are use multi sig address i think you can't do signature message, better you use blockchain address or new address from vanitygen
