Pretty much always fake. While the “risk” of using my real name is probably small, there’s also very little benefit to me personally if people knew who I really was, so why bother.

Exceptions: Github, maybe Stackoverflow, but it’s been a while since I’ve posted there.

I grew up on the internet in the 90s and early 2000s and the general rule then was not to give out your name and info. So I just keep following that.
