The measure I would actually check on dating.com free credit is how well it holds up once the novelty fades.
I gave dating.com free credit about 5 weeks before I formed a view, mostly watching whether messaging costs anything once you start.
If you care about whether appeals go anywhere, that alone should decide whether it's worth it.
My rule for the platform now is simple: check how much of it is usable without a card on day one.
