Out of the top of my head I'd say:
solo girls: Mutt (Pseudonymous as a very close runner up)
interracial and cuckold: Dig420
smoking fetish: MikeS
goth, alternative: AmeliaG
asian: ADG
everything: Paul Markham

Not trying to leave out anyone, just the first popping out for me

fell free to add more niches and/or names
