Showing some example of particularly egregious thought leadership and maybe an animation of it being silenced would go a long way towards helping. I blocked twitter.com in a hosts file, so I can't see if it embeds any tweets.

I'm curious how you managed to block twitter? Somehow when I add twitter.com to my /etc/hosts it doesn't seem to have any effect.

Check the bottom of the list for the social ones.
