I'm a webmaster, so I'm sensitive about such issues, and I contribute to the EFF, which your post eventually links to:
http://www.eff.org/deeplinks/2010/01/order-shut-down-websites-critical-apex-technology-In the interest of full disclosure, I also think the H1-B policy should be revisited, as I happen to, indeed, think it's used to keep skilled worker wages down.
The fact is that the issue at at hand is NOT some posts on some BBS, which the webmasters failed to delete. Rather, it was things which the webmaster(s) themselves were stating which were, indeed, defamatory and if true, criminal about the plaintiff.
You can say someone "sucks" and they're "wrong" about something, but you, the webmaster, can't post private, internal documents (I'm sure there was some non-disclosure agreement?) and then charge H1-B companies of "fraud", fraud being both a civil violation and crime.
I'm actually for the side of the webmasters here, but not the way they conducted themselves. I don't like playing a lawyer when it's "just us" talking, and I understand wanting to get people's attention by being sensational.
But when you post something on a website you simply have to give yourself some weasel room, and it seems these guys didn't get that.
