Ask HN: Anyone Interested in Capture the Flag (CTF) Events?

there have been some great CTF[0][1] links here in the past[2] but many of them are from 5 or even 7 years ago[1].

Anyone still actively playing CTF in 2019 and if so what is your experience? Anyone here hosting CTF themselves? Anyone providing advanced puzzles (hardened systems that have no built in flaws?) Anyone building CTF puzzles for IoT? E.g. focus on gateway level protocols such as MQTT, COAP etc?

I played a few times until 2009 but then had other things on my plate. What are the latest & greatest communities today?

thanks ^_^
