After my recent request for feedback on used parts networks, I sent out requests to BreakerYard and PartsGateway, giving out tailored email addresses to both. The results are now in:
Neither managed to find a common part for my car
I have received spam on the email address I gave to BreakerYard
On the email address I gave to PartsGateway I have received phishing including my name and address, and a message about 'we'll send your items as soon as possible', with the payload being a link to click about 'order details'. The link says 'customer confirmation' and looks like it's a personal website on a hacked server.
That's two out of two.
So the conclusion is: don't use these networks because they will leak your details to spammers, if they aren't spammers themselves. They're not just a complete waste of space, they're actively malicious.
