Wait, you're the paranoid one? Nah, you're the one who almost got scammed and got lucky. But here's the thing, most people don't have time to run every listing through a registry. That bike could've been totally fine, and you just scared yourself out of a legit deal. I've bought like five used bikes off Craigslist and never checked a single serial number. Some sellers are just weird about questions because they don't know the answer, not because they stole it. Plus, stolen bike registries are spotty anyway, half the stuff on there is old or missing photos. You're basically trusting a random website over your own gut feeling about the guy. If the price is too good and the person seems sketchy, sure, peace out. But missing a good deal because you're scared of a ghost story, that's on you.
