I think it more so derives from the same place Q derives from rather than deriving from Q himself.

Chanboard users refer to each other as anons. I am still somewhat confused, as the conservative would presumably refer to op disparagingly as a “blue[British word for ciggie]” as opposed to “blueanon”, seeing as how “anon” has connotations of comradery. This is further compounded by the fact that we have usernames. We’re not anonymous. We’re pseudononymous.

If I had to guess, this is due to moderation preventing the use of slurs in regular speech in most regions of Lemmy.
