Thank you for your answer, after your comment I really started to think the problem was on my own side, and it was actually.
I connected to my account directly on the lemm.ee’s website, and I changed my password, just to try and see what happens, and it worked !
I tried to login in Mlem directly with your recommandation for the fields and the new password and it was successful first try
Sorry to have bothered you and thanks again for your help
First, from a purely technical perspective, there is absolutely no way this works properly, you just can’t recognize a trans person just by looking at his/her face, even if this was ethically okay (and this isn’t), it couldn’t work at all.
Second, the privacy nightmare that would be, every picture of everyone would be processed (and certainly stored forever for training the program) without the possibility to disable it ?
And finally, the obvious discrimination against trans people (I never encountered a trans person that wasn’t honest about it, so it’s even pointless to "detect" them)
To be honest I’m not in the LGBT community or anything, but this goes to far
