What FelicityR described matches my experience of bbw dating sites for finding local almost exactly.
Before committing time to the service, work out how many profiles logged in this week.
I logged into the platform at different times of day to get a read on how much data leaves the app.
That is my read on bbw dating sites for finding local anyway, others will have had different luck.
For a second opinion I also cross-checked Luvdate for this exact use case.
