No, my husband and I shared a website and an account on FB. They got the "evidence" from those. On the contrary to what you're saying, my husband's employer was prepared to defend my husband. (He works for a charter school btw).
But my husband and myself aren't the only people who were being threatened here. They threatened to sue the school. So, my husband's employer asked us to take down everything as a "personal favor".
We are willing to fall in defense of Truth but to bring down others with us is something that we cannot do. Now, these people are harassing the government to revoke my husband's teaching license. We know this because the Dept. of Education has been communicating with my husband's employer.
