Tried it once or twice, got close to zero attention every time and once in Austria I actually was about to meet someone but they ghosted me.
So I stopped bothering with it.
Searching literally anywhere else resulted in better findings for me.
I'm so close to creating an online dating profile to get into the pond and get to know new people, so I'm interested in your experiences. Do you do it or have you done it in the past? Have you been successful? What are good photos to choose?
And no, I won't post this on /kb/, which nobody even visits.
