Nobody will do this, no sane legal department signs this off or approves of such behavior. Doing otherwise is a great way to incinerate their legal licenses. There are fines for behavior like that.
The best outcome for the suing party of such a scenario is a 5 minute court room appearance in which the judge slaps you with a restraining order and closes the case.
This has literally never been an escalating problem in european courtrooms to my experience because judges don't like that behavior and laws exist to prevent it.
