Regarding point 2:

https://en.wikipedia.org/wiki/Poe%27s_law

Poe's law is an adage of Internet culture stating that, without a clear indicator of the author's intent, it is impossible to create a parody of extreme views so obviously exaggerated that it cannot be mistaken by some readers for a sincere expression of the parodied views. The original statement, by Nathan Poe, read:

    Without a winking smiley or other blatant display of humor, it is utterly impossible to parody a Creationist in such a way that someone won't mistake for the genuine article.

Poe was simply reiterating common advice about the need to clearly mark online sarcasm or parody (e.g. with a smiling or winking emoticon) to avoid confusion.
