My screen-names associate more with my hobbies and my obsessions or whatever was in my mind at the time of their creation.
However, I more often than not associate with my real name, at least, my first name.
My github is the only one of my (public) online accounts to officially integrate my real name. But, it retains an element of my usual name-creation technique:
<real name> + 151 (context: pokemon, so mew's #)
However, on either content I've submitted, or in my bio/about sections of a given profile, my real first name is...somewhere.
(tbh, kinda tired of my dorky screen-names...lol)
