It's just as provable as a loan in the first place.
If the person hasn't sent the agreed amount, and they have enough in their account and alt to compensate the loan and meet the profit requirement, then a TSA should send the TC up to the profit mark. If they don't have the TC, compensate with items to meet the profit mark.

It's just another form of generating income, it's already hard enough to do, limiting options for no reason seems just.. bad taste. Enlighten me if there's actual reasons behind it that this suggestion doesn't cover

Lots of loans don't get returned and the account that is scamming doesn't have anything at all on it. No TC, no items.

It's not unlikely that you get scammed when loaning, so giving an incentive to loan (random) people is not a good idea in my opinion.

I don't see loans as form of income, I see them as a friendship thing.
And in general, do not loan TC you can't afford to lose.

Why should you guys monitor such things? Allow us to loan at our own risk. Your viewpoint is fair, you are allowed that, but others see other perspectives.

There have been times where I got my loan returned for only the amount I loaned them, not the profit, and they definitely had the TC to actually pay the profit as well, which is frustrating. Like I said in the OP : if they can afford to pay the profit discussed, there is absolutely NO reason to keep the profit from the loaner. It's cool that YOU think it's a friendly thing, some others, like myself, would like to use it for profit and have the security of that.

I think what you suggested sort of already exists though. I mean, you can clearly loan at your own risk and people who do loan scams get banned. As for supporting profits, it's quite irrelevant in my point of view. If a person loan scams, it's almost always because they don't have enough TC/items to repay it. I doubt you will ever stumble upon a case where person that loan scams has anything worthy in their inventory.
