Firstly you have negative trust and on top of that NO FREAKIN collateral! And you expect someone to lend you 1 eth without any guarantee that you'll return te loan back in time, or ever return it.
This could result in a ban of your bitcointalk account. So better you comeback with a collateral.
Asking a non-collateral loan does not result in ban. It results in a negative trust from DefaultTrust on the (would be) borrower's account specially if the asking party is a newbie with no prior positive trade history.
There are many people who have a good reputation here (example Darkstar_ , aTriz) and they are entitled to take non-collateral loans because defaulting it will end up in them losing their services and reputation here. So the borrower has a bigger security that the borrower is already trusted here.
