"Greater Internet Fuckwad Theory" was both a lie (typically invoked to defend/justify bigotry, bullying, and such) and it also served to normalize people being assholes on the internet. "Perfectly well adjusted wholesome ordinary people chant nazi slogans when they log onto the internet, for real guys! It says nothing about their character as people because for some magical reason the internet totally has no connections to lived human experiences!"

I'm glad that the so-called rule fell out of use and the excuse rings very hollow for most people now. Also, I noticed that many "ironic asshole" comedians and entertainers from the "le epic trolling" era wound up being actual assholes that hurt people outside of the act. "Million Dollar Extreme" and Justin Roiland come to mind.
