I agree OP is probably a troll. But just in case he isn't:
OP, just because someone ratted you out to EDD and your employer doesn't mean it's the forum's fault that you lost your job and EDD benefits. It's your fault you lost your job, by badmouthing your employer on the internet. And it's your fault that you lost your EDD benefits, by going to Nevada.
Regarding your anonymity, no one is truly anonymous on the internet. It's not the forum's fault that someone had the tech savvy and diligence to find out who you really are, it's your fault for posting inflammatory things on a public internet board.
Regarding your family, what? You were badmouthing them too? No wonder they don't want to have anything to do with you anymore. It's not the forum's fault that your family found out how you really feel about them, it's your fault for publishing said feelings.
Finally, that forum's TOS probably states somewhere that no threads will be taken down no matter what. You agreed to this - it's not the forum's fault that you later changed your mind.
