     Pinchanzee Chris from Scotweb:
Luis brought our attention to a security vulnerability we had overlooked. We were unfamiliar with OpenBugBounty so thought it might be a scam, but upon contacting Luis he explained the problem clearly. He even offered to help fix it (but we had the facilities to fix it in-house). Very grateful!
