As a rule of thumb, if you ever have controversial media, be sure to at least have a trusted friend out of the US to have a copy. Probably more than one person. So if you are slapped with this injunction, you can just shrug and tell the judge that many copies were distributed “to persons unknown” before the injunction, so you no longer have control over them.
“But we will obey your injunction, though it is moot.”
Doesn’t even have to be outside the country. The injunction binds only the named parties to the suit and those “acting in concert” with them. If the video has already been uploaded to the internet, anyone but the named parties can freely distribute it.
