The classic trick was asking for a photo that has any specific word you ask to put in that photo. But I guess that can be generated in real time. In any case I've spent a long time trying to develop genuine connections with people online and it's really not worth it unless you have money to travel all the time.

Best way for connection is real life interactions but society doesn't build centers for everyone to go to anymore. Real life is just work work and meet someone whose already married and only thinks about their kids. Basically nothing... But loneliness.
