I don't your name, pc86, is a real name, too. That's the life of them internet. So much about Pseudonym. So if already the very first statement is that questionable, how can I believe the rest you write had any truth?
The GP seems to use similar naming conventions for all their accounts. GitHub, HN, Twitter, are all "lhecker." It's a pretty standard naming convention - I'm pcopley on a ton of services. So I can see how it could raise an eyebrow when you get an aberration of that norm or habit or brand or whatever you want to call it. The simple (and honestly maybe even likely) explanation is just "it's not an anonymous account I just have a different username on discord." But if you're inclined to pick up a pitch fork every now and then it's easy to take that as some sort of nefarious act.
