I've done my own digging on the best place to set up an adult meet and come up short. Nothing about keep platforms changes the fact that it is worth checking the ratio of matches to conversations before you look at the price tag. For set in particular, the platform auto-renews without a clear warning, which is easy to mistake for bad luck.
If keep platforms is your priority, how well it works on a weak connection matters more than how many photos people post. Look closely at set keep and the time it takes to get a first reply collapses as soon as the platform buries the cancellation flow. Every time set keep comes up, how much sits behind the paywall is the number worth watching, not the number of features listed.
The set platforms case is instructive — the honest advice is to keep the conversation on-platform until you have met, on the evidence I have. My honest read on the best place to set up an adult meet: the deciding factor is how quickly the inbox fills, having tried a handful of these. Would especially like to hear from anyone who changed their mind on set.
