Keep in mind that having a "false identity" does not make you a malicious actor. I have a serious project I work on under another pseudonym, but it has to do more with the fact that I do not want my real name to be associated with that project AND having a serious case of impostor syndrome. :/

That, and I used to contribute to various games (forks of ioquake3) when I was a teen and I wanted to keep my real name private.
