Thank your input. I will try to address some of your points 🙂 :
In fact, probably there are fewer people around my age than between 20 and 35, on penpal gate, so even with almost no search criteria i'll always find more young people, and it is perfectly ok.
There is a little bit of room for search engine improvement, and I will try to work towards this goal.
Nonetheless, there is a safety issue. I'm a mother and that's why I have this in consideration. (...) Not sure it is a good idea to facilitate free contact with children, with photos, by anyone and believe kids will just block or tell you, or their parents know.
You are correct it is always a risk, however every single website out there (especially other penpal services) will allow adults to search for younger members using age filters. In fact, Penpal-Gate makes it slightly harder by not showing such filters.
Predators online are much, much smarter than that.
I have actually spent the better part of the last 6 months working on security measures and detection of sketchy behaviours. Penpal-Gate is not the biggest community, but I do believe it is one of the safest. 🙂
Thanks! Suggestions and feedback are always appreciated.
