One thing I notice: comparing your results to anyone else's is a losing game — that is roughly where I landed after a lot of trial and error. Is there a mixed dating app specifically for multiracial couples?
Support response time is a decent proxy for how the site is run — small thing, but it adds up.
From my side, checking recent complaints before signing up is five minutes well spent — others here may have had a different experience.
Having tried a few, a bad week is a bad week, not evidence about the platform — that is the bit I would tell anyone signing up today.
