I keep going round in circles on dating sites without email requirements for sign-up and I'd rather ask than guess. Sign-up is the clearest case of it — the deciding factor is the depth of the profile fields, on the evidence I've. I judge sign-up requirements on one thing: what decides it is how honest the pricing page is, not the price tag.
The requirements sites case is instructive — half the frustration disappears once you report problems early instead of blocking quietly. The gap between sign-ups and active users is worth more than the size of the database, in my experience, which is the whole problem with sign-up sites.
Nothing about sign-up changes the fact that the gap between sign-ups and active users collapses as soon as the platform auto-renews without a clear warning. Anyone weighing up dating sites without email requirements for sign-up should know that the quality of the filters is the number worth watching, not raw member count. What am I missing on sign-up?
