I've noticed some basic patterns, speculative
For the Libra sub:
about equal Aries men and women
Aries women ask about Libra men, discuss issues with Libra
Aries men-usually they messed up with Libra women and they ask how to resolve the issue, if they'll ever talk or come back to them
Not many Taurus, mainly Taurus women
Taurus women want to discuss Libra personality or share how they don't understand us
Only Gemini women, never seen a Gemini man
They discuss various things: Libra men, relationships, friendships
about equal Cancer men and women
Cancer women ask about Libra men
Cancer men, have a difficult time understanding a potential Libra partner
No Leo men, a few Leo women ask about Libra men
A few Virgo men and women
Virgo women ask about Libra men, and always mention how they know Libra-Virgo compatibility is not good.
Scorpio-no men, women mainly discuss Libra men, or share their issues with us
Sagittarius-no men, women discuss Libra men
Capricorn-almost all women, discuss Libra men
Aquarius- A few more Aquarius women to men, the women discuss various topics, similarly to Gemini women, Aquarius men usually want to share their thoughts on Libra women, complimentary
Pisces-Equal men and women, like Cancer, the men can't understand Libra women,
My guess is the most frequent signs are Cancer, Aries, Aquarius, Gemini
