I kind of doubt your story as presented. I repeatedly make inflamatory posts on Digg, have for a LONG time, usually much more offensive and obnoxious than anything here on FR (other than accusing another member of performing abortions in his car and telling the mods to go 'f%%%' themselves).
My accounts on Digg routinely post conservative stories all the time.
ARe you sure you didn't post something really against policies? What's your screen name?
