After 21 years on the Internet, joined who knows how many discussion boards, I finally got kicked off a board - Democratic Underground. All I did was to post limited quotes from a website that said people were leaving California. I never said in my post that I agreed with what the article said.
I guess some HSP (hyper sensitive person or persons) from the Golden State got offended.
By the way, I tried to re-join DU and I keep getting rejected. I guess their software can track whatever IP address you're trying to join from. I even have a VPN, and that doesn't seem to stop them.
