Injunction is a way to prevent more damage from occurring. So generally speaking, injunctions : 1) are only available either during a trial or as a last resort (if you can make a good case the defendant won't pay even if the judge compels them) 2) you'd still have to prove more damage will be done if injunction isn't there. Those have to be real damages, with real monetary amounts on them. This is western law, it's practical. Anything you do that either doesn't bother anyone, or you prevent damage from occuring is legal, no matter how much it is against (civil) law. The fact that something violates copyright, by itself, is not sufficient to get anything done in court at all.
