HarperTX covered most of it. The bit I would add on flings dating site is below.
I would judge the site on how well it holds up once the novelty fades rather than on the feature list.
Ran that one alongside two other options for a month, tracking how many profiles logged in this week.
If you bounced off this before, revisit that one and check how long a bad account stays up first this time.
What separates flings dating site from the rest of the field is whether the search actually respects what you set.
Widening the radius on that one added volume and quietly worsened whether the recommendations improve with use.
