I don't know what the right way to handle intersecting identities is.

Most of my online identities were started when I was in college and was happy to have them tied to my real name. (This is also when Facebook was popular, still good, and college-kids-only.) Since then, cancel culture et. al. has made me more wary of having my identity-adjacent usernames show up in hobbies like gaming.

If I want to be myname in some Discord servers and anonoguy in others, is there a safe way to enforce that boundary? What about if I want to work on gaming-related open source projects or 3D prints?

As the internet moves to logged-in-and-social-by-default, it's hard to know which identity to use for which service. Moreover, when things are constantly leaking/being hacked, I don't know that I want any service to know that anonoguy and myname are personas of the same individual.

And as LLMs become the standard, I'm not sure any of this is defensible. I imagine in a decade's time, it will be trivial for an LLM to go "this account and that account have similar interests/references/ways of typing - they must be the same person."
