The opposite side can still technically put in a picture of a potato for the so-called fair trade and you are still gonna be so pissed that you couldn't help it but involuntarily leak,like, nonstop.

The simultaneous (“fair trade”) exchange of locked pics is a decent idea, although it involves an additional transaction, either by a human or IT program, and likely would take longer to accomplish. I too have had guys you didn’t unlock after I unlocked mine to him. I’ve reminded such persons, and they usually complied, probably merely an oversight on their part. If they, once reminded, don’t unlock their pics to me, that tells me enough about them that I know they are unreliable and not someone I care to pursue.
As to posting by member Flores, if I understand you correctly, the unlocked pics of two different members are not always comparable.

What if we did unlocked back and the person's bio/description of themselves didn't match their unlocked pics and now we have unsolicited pics that we just wished our eyes hadn't seen that and someone having a pic of me on their electronics probably looking mighty fine naked.... Basically to not allow screenshots, download/save, screen record

Because also sometimes even if we do both unlock the others unlock picture doesn't even match my picture; sample like I send a fully naked pic and the other persons picture is a dick pic of him showing with cloth on

Great idea for fair sharing pics
Hope from programmers also to ensure everyone is sharing his own face pic
It’s important

I have never seen so many people so serious about something that is for entertainment only.
