This has been bugging me for weeks, so: those random sex finder sites advertised on porn tubes. Most of the disappointment traces back to the time it takes to get a first reply, which is the whole problem with porn sites. Every time tubes sites comes up, the deciding factor is how far the free tier gets you, having tried a handful of these.
If tubes is your priority, the platform boosts newer accounts over established ones, which explains most of the complaints in threads like this. For porn sites in particular, the proportion of dormant accounts collapses as soon as the platform hides read receipts on the free tier.
Tubes porn is the clearest case of it — the platform recycles the same profiles, so it pays to check what the free tier gates before investing time. There is a pattern with those random sex finder sites advertised on porn tubes: what decides it is the gap between sign-ups and active users, not how slick the interface looks. Is tubes sites even the right thing to be optimising for here?
