Bad traders

FWIW, as someone that's donated to the site, I assumed my identity was known anyway

Only if any donation was made from the same email that is used on the site.

But that's still beside the point... the good guys are fine, it's how the bad guys use the behaviour of the good guys to do bad stuff that is the issue.

The difficulty I have is how to help people buy and sell stuff, but to prevent the bad guys getting away with stuff. As a forum we are largely successful in stopping bad guys, i.e. by others having this discussion and flagging this behaviour.

The benefits of PayPal, Monzo, in-person stuff... is really that the whole marketplace is more trusted and more successful if we collectively shut down bad guys by making it really difficult for them.

But yeah, not banned it yet... but it does concern me, so do look for better ways. The monzo thing is good, it's basically a pre-paid card, easy to charge and send money, easy to receive and use the money. They'll soon be a full bank which will make it even easier (and is what I'm waiting for before recommending it widely).
