What is the Best Practice Procedure for Documenting Social Media Evidence from Communities on Facebook, Telegram, etc., for Use in Legal Cases?

Hi everyone,

I understand that the law of evidence varies from jurisdiction to jurisdiction. However, I am looking for a general procedure or methodology for documenting evidence from social media platforms where groups and communities operate, such as Facebook, Telegram, etc., in a way that could be used in a court of law.

The documentation may be used to build a legal case or even to create a human rights advocacy case.

I understand that simply taking screenshots or recording a video is not going to be sufficient evidence in court.

Could anyone recommend a proper procedure, methodology, or OSINT best practice for documenting and preserving social media evidence?

Thank you.
