A: You actually raise a couple different issues here. 1. Can Court documents available on PACER lawfully be disclosed on social media? Yes, because they're public records, and the fact that the discloser is a lawyer who is not on your case is irrelevant. 2. Can someone lawfully make fun of you on social media making reference to court documents (and what if that person is a lawyer)? That depends entirely on what you mean by "make fun of". Whatever they're doing may or may not violate Fla. Bar rules of professional conduct. You can ask the Bar. Also, whether the perpetrator is a lawyer or not, spreading false information damaging to your reputation could be actionable defamation of character.
A: Interesting issue, which I don't have expertise in, but my somewhat-educated guess is: Regarding the issue of disclosure itself, without regard to whether it causes damage to the corporation, the answer to your question may depend on whether your corporation has a written confidentiality policy, and if no general policy, whether the particular matter was specified to be confidential. Regardless of whether it's required to be kept confidential, if a disclosure (without board consent) causes any kind of damage to the corporation, there would likely be avenues for legal relief, starting with petitioning for injunctive relief (order to cease & desist), and the corporation could try having an attorney send a cease & desist letter. Also review the incorporating documents (articles of incorporation and bylaws) for grounds to remove current board members. I hope a lawyer with expertise in your issue chimes in on this one, but regardless, it'd be best to schedule a consultation with a lawyer in your area handling corporation formation and litigation issues to solve both the issue of problems that already occurred and the issue of preventing problems from occurring in the future.
