It's not that hard to spot when someone really needs a legit loan, even withouth collateral in some cases. If the member can sign his old btc address, and the
amount isnt a great one in contrast to his/hers account, i believe they will pay up.
If that sort of rule was to be used, then one could argue that no escrows should be trusted, since they also can sell their account and take the escrowed funds to themselves,no ?
Accounts are nowadays sold with the old private keys. You will
not know if he really is the old owner.
And the worth of the account is nothing you can trust on if you don't take a collateral. Since what will you do when he sold his account after you gave him the loan? Will you try to get it from the new owner? That's an unsure game.
You really should not be so uncautious. You ask for being scammed. I say that because this happens on the forum, this is no theory.
Of course you need to not trust escrows, though most escrows are trusted because they have shown some form of morals that would make it unlikely that they will sell their account for a fraction of a bitcoin. And accounts asking for loans are only in very rare cases so established or trusted like escrows.
On top, escrows often had way way more coins in escrow than a loan or account can be worth. So if an escrow would want to scam then surely that would not be for the amount of loans that are lent out on the forum.
Don't feel so safe. If you behave that way then you will bring escrows in risk too. Since when they get tricked by the scammer then it might be that they pay in order to not tarnish their name. It might be that some of these no collateral loans only found a good ending because escrows paid, because they felt responsible.
Only saying...
