eighty-twenty.org is a personal blog by Tony Garnock-Jones, primarily covering programming topics like teaching languages and IDEs. It's been around since 2004 — a strong sign that it's not fly-by-night. The site uses a proper SSL certificate and loads quickly. However, it appears on one spam blacklist (Barracuda), which could be an old false positive or a sign that the domain was once used for questionable activity. We didn't find any other risk signals: no malware, no phishing reports, and no hidden ownership tricks. For a personal blog, missing legal pages and social media are normal. If you're considering registering or interacting with the site, the blacklist entry is a mild caveat but not a deal-breaker. Most older personal blogs with this kind of history are legitimate, and eighty-twenty.org looks like one of them. Use your own judgment, but the evidence leans in favor of it being safe to browse.
