While I am not currently happy with this company or the CEO, I do not agree with any personal information being shared, or any harassment of the CEO or his family. I think most people ignore or report any inappropriate posts, but I would recommend that everyone report those posts to any message board they appear on.
Not agreeing with the CEO or not liking him because of the way his actions are perceived should NEVER equate to threats, violations of his privacy, or the gathering of content from his family members. If I see these things, I will report them as I think we all should.
