For what it's worth, the older established sites have moved the useful bits behind a subscription, and nobody warns you about it. What are the legitimate dating sites — figured this community would have the most honest answers.
- Honestly, the read receipt setting is the thing that decides it, although most of the free apps rarely say so
- Judging by my own inbox, the photo review is the thing that decides it, even if the ones with a paywall rarely say so
- The part nobody mentions is that the niche ones have tightened up the reporting flow since the last round of app updates
My advice would be to skip anything asking for a card number to read messages and then read the last few pages of a thread before asking, which is worth knowing before you sign up.
Judging by my own inbox, if your inbox is dead the answer is usually to use a recent photo with your face clear rather than move to a proper conversation quickly. Speaking personally, most of the free apps have made the first message cost something, which explains a lot of the complaints here.
