Was first tempted to say GOG may want to look into the loophole, but it does say "with some payment methods", so guess it's intentional, when using another step that's considered to have already vetted the purchaser.
As for zeo, patience, been times when he took 2 weeks or so to get around to the giveaway again. Does take concentration and organization, so when otherwise busy makes sense to set it aside even when you can be around to write a few messages in other threads, this is quite a different responsibility.
