Fencer: It's not a contradiction.
It seems to me you implemented AutoPass as a game setting. The game either uses AutoPass or it doesn't.
For us that are arguing for the "without aggreement from both players", we see this setting as 2 settings for each game - white is using AutoPass / Black is using AutoPass.

I don't need to know if my opponent is using AutoPass or not - the only way I'll probably know is if I play and the game comes right back to me (and even that depends on how I sort my games). This in no way affect my play (well, actually it does - I do all my moves at once until the games reaches a state where my opponent can make a move on his/her own - making it last longer on those moments where we are really playing and not just throwing the game back at each other).

With the dual setting, I'm not forced to use AutoPass and my opponent can. Is this one setting / dual setting issue related to your problem with the "without aggreement" thing?
