You actually asked them why they banned you?
Yes.
They said they had gotten “innumerous complaints” and reports of abuse.
I was extremely PC, never a bad word, never an attack on Islam or whatnot, just very high profile and stating facts in response to repeated lies (e.g., stuff like “Israel drove Palistinans from their homes, intentionally kills civilians, etc.)
I suspect a pretty organized “go complain about XYZ he’s a conservative asshole” campaign that liberal Digg doesn’t investigate much.
