<human>: Throw away because I am sure some people involved are also on reddit.

Essentially, a 20 year old person (they say they are gender neutral) has accused my friend, and many others, of assault. They have created a FB group that is based around the idea of keeping conventions in our area safe from these people. This person does not have a degree, but keep saying they have a history in abuser psychology. They say they have been trained to tell if someone is lying "about these sorts of things".

The main issue is this: my friend, Jack, is innocent and on this list. He does have a spotted past. His ex-wife did have a restraining order against him for a short while, but she posted to the group explaining the circumstances and that it was her father who made her file it. She did not file the restraining order because she felt she was in danger. Her father had her file it while she was getting sober.

A friend of Jack went to the police head quarters and paid for his permanent records -- he then posted them to the group as proof that Jack is innocent. He does have a few DUIs, the restraining order, but nothing to indicate he is dangerous or a predator.

The person running the group refuses to remove Jack from the list.

Jack has close 1000 friends on facebook, as he is rather popular in the convention circuit in our area. Many of us have been reporting the group, and nothing has happened.

Can you summarize the given text in a few sentences?
<bot>: My friend has been wrongly accused of having multiple assault allegations against him, and is being threatened to be banned from local conventions. What actions can we take to stop this, and to protect him?
