I helpfully added to the end of a comment, "If you see a Nazi, punch a Nazi", as a play on "If you see something, say something." That got me a one-week suspension. A couple of weeks later, I posted a link to a site that explains how many of the top corporations are owned and controlled, through stocks, by a small group of the same billionaires--they all sit on each other's boards and block outsiders from being elected. That got me a permanent suspension. I haven't been back.

This was on my account that is eight years old, and had over a million comment karma, and about 40,000 post karma. Fuck 'em.
