Having tried a few, the people posting about success are a tiny and unrepresentative sample — that has been consistent for me across a few different platforms. Are there any female dating sites where women have total control over messaging?
My take: the profiles that get replies are the specific ones, not the polished ones — your mileage may well differ.
Broadly speaking, results vary a lot and a quiet fortnight means very little — others here may have had a different experience.
