I think no site is safe, they already know who you are through various data collection points such as Blogs, myspace, facebook, youtube, google etal. In my experience of forums you are always going to get those who like to disrupt threads cause animosity and spread BS. Hopefully as a community who have followed Bill and Kerry's work with project Camelot and using our common sense we will be able to spot any disruptive disinformation agendas and weed them out.
Peace & Blessings
