I picked an RNG name since my old common username (from reddit, etc) was not available when I started on kbin.social (RIP) and I couldn’t think of anything else I wanted to be called. I deliberately kept it short though. Not sure what to make of other RNG names – esp. long unintelligible ones – but I’ve seen at least one account that I think is legit which has a long, bizarre RNG-looking username and a non-English display name, so 🤷️
