I chose my words carefully.

Invading means to enter, and he didn't enter anything. He posted a link through Facebook's buggy system. The end.

Yeah this sounds like a super productive discussion.

Especially when you start using argument tactics like belittling.

You're right; I am officially derisive of this discussion. You know I'm not making an argument by trying to characterize this person's actions as malicious, but you keep raising that idea as an issue, because you actively don't want to understand what's happening in this situation, but would prefer instead to demonize Facebook's security team.

Demonize the security team? I never implied that anywhere - please don't "put words in my mouth."
