So. If a user Skypes me and verifies my identity, I can magically steal theirs! Because fuck logic
I didn't say anything about stealing identity, you're twisting it again. Learning someone's identity and stealing it (i.e. impersonating) is not the same.
And yes, if e.g. I would skype you, you could learn my identity. I think you even admitted yourself somewhere in this whole shitshow that Skype is not good for anonymity, I just can't be arsed to find it now. So no reasonable person would do it and you know that. You're just looking for idiots now or playing some game where you'll claim a win because no one else wanted to participate.
